1 Introduction

Concrete is considered to be the fundamental and an im-portant material in construction industry Maintaining andtesting the quality and behavior of concrete is the challengefaced by the industries in recent times Also the modeling ofmaterials through regression tools and AI tools is recentlyincreasing due to its accurate prediction and evaluation econcrete as generally known for its good compressive be-havior is made to behave well under tension and flexurethrough addition of fiber additives e general tensile andflexural strength enhancements are made through additionof fibers made up of various materials with different physicaland chemical properties e addition of fibers made up ofvarious materials changes the behavior of cement-basedcomposites and enhances the toughness tension re-sistance and flexural resistance [1ndash9] ese fibers act atvarious levels in altering themechanical behavior of concreteand thus defy the rules framed for its tensile and flexural

performance making it hard to predict e major factorsthat act in enhancing the tensile and flexural strength arefiber distribution and its physical parameters In recentyears analyzing the concrete properties through predictionmodeling is gaining importance due to its accuracy andeffectiveness in real-time applicationese concrete modelswere presumed to predict the strength development throughcertain factors which are used as input parameters isprediction facilitates in making decision on concrete mixand material selection [10ndash15] But there is a challenge whencreating a model of concrete for predicting tensile strengthand flexural strength as an effective prediction model is notcreated through parameters which were used for predictingthe compressive strength [16ndash18] e challenge on accuracyin prediction increases in fiber admixed concrete whilepredicting tensile strength and flexural strength this is dueto the fiber properties and its distribution

network (ANN) e fiber properties were used as param-eters along with basic concrete and fiber parameters withsingle target system and the model is tested through sta-tistical tools for its performance

2 Prediction Modeling and Testing

e model created here is for fiber-reinforced concrete thedata set was collected for steel fiber polypropylene fiberhybrid fiber glass fiber and basalt fiber from early studiese actual compressive strength split tensile strength andflexural strength are taken as the target values based on thefollowing parameters which are used as input parameters

(1) Tensile strength of fiber (F)(2) Percentage of fiber (P)(3) Watercement ratio (R)(4) Cross-sectional area of test specimen (A)(5) Youngrsquos modulus of fiber (Y)(6) Mechanical strength of control specimen (S)

Based on the input parameter and target values theoutput was generated through ANN and MRA and theseoutput values were compared with target (actual) values etypes of fibers and its respective literature source are pre-sented in Table 1e active compressive strength data set has5 columns and 252 rows (5times 252) of input data and 1 columnand 252 rows (1times 252) of target data e active split tensilestrength data set has 5 columns and 119 rows (5times119) ofinput data and 1 column and 119 rows (1times 119) of target datae active flexural strength data set has 5 columns and 150rows (5times150) of input data and 1 column and 150 rows(1times 150) of target data e target data for compressivestrength split tensile strength and flexural strength were usedin both the MRA and ANN model as separate target in thisstudy is single target system was used due to the usage ofcross-sectional area of test specimens as one of the param-eters and it was known that the shape of the specimens varieswith different mechanical strengths

21 Prediction Model and Its Statistical Test Two predictionmodels artificial neural network (ANN) and multiple re-gression analysis (MRA) are used in this study to predict thecompressive strength split tensile strength and flexuralstrength of fiber-reinforced concrete (FRC)

22 Artificial Neural Network (ANN) e ANN predictionmodel is programmed through MATLAB with two hiddenlayers 15 neurons in each hidden layer and one output layerwith dependent variable as compressive strength split ten-sile strength and flexural strength Among all the data ap-proximately 70 15 and 15 has been considered fortraining testing and validation respectively e LevenbergndashMarquardt (LM) algorithm is used for training due to itsrobustness and speed Layered feed-forward networks havebeen used in this algorithm in which the neurons are arrangedin layers Here signals are sent forward and errors arepropagated backwards

23 Multiple Regression Analysis (MRA) In this study thelinear-type multiple regression analysis modeling is carriedout using MS excel e coefficients of regression are cal-culated by considering 95 confidence level hence the errortolerance level is limited to maximum of 5 For a giveninput variable the calculated probability value (p value)is considered to be significant if and only if its value is lessthan 005 rough the regression analysis the followingcoefficients presented in Table 2 were found and substitutedin linear multiple regression equation (equation (1))

output I + C1F + C2P + C3R + C4A + C5Y + C6S (1)

24 Statistical Test e performance of the ANN and MRAprediction for the mechanical behavior was tested throughthe statistical methods e tests involved are coefficient ofdetermination (R2) and root mean squared error (RMSE)e coefficient of determination is presented in equation (2)is can be obtained from the comparative chart of pre-dicted compressive strength vs experimental compressivestrength e accuracy of the predictions of a network wasquantified by the root of the mean squared error difference(RMSE) between the experimented and the predictedvalues and the procedure of finding RMSE is presented inequation (3)

3 Results and Discussion

e effectiveness and the acceptance of prediction modelsare based upon the ability of the model to predict the outputIn this study the models were designed to predict themechanical behavior (mechanical strength) of FRC based oninput parameters and two methods of predictions ANNand MRA are used e prediction models are validatedthrough coefficient of determination (R2) and root meansquared error (RMSE) and are consolidated in Table 3

e MRA and ANN prediction of the compressivestrength value is plotted with respect to the actual compressivestrength and presented in Figures 1 and 2 respectively eMRA prediction has the coefficient of determination R2 as093 which is almost an acceptable value whereas the ANNhas an R2 value of 1 which indicates that the ANN model isaccurate e RMSE of the MRA model is 723MPa and theANNmodel is 014MPa which demonstrates that error in theMRA model is large and cannot be relied upon for predictingthe compressive strength

e MRA and ANN prediction model plot for splittensile strength with respect to its actual value is presented inFigures 3 and 4 respectively e R2 value for the MRAmodel is 087 and ANN model is 094 e RMSE for the

exural strength was also of higher accuracy ough theshybers have various factors on inuencing the strength de-velopment in concrete the prediction models MRA andANN are accurate by its output values e ANN eventhough has its advantage of higher accuracy over MRAmodel the performance of the MRA model is also eciente contribution of shyber properties in the prediction modelproved to be eective and also gives more preciseness to themodel Earlier models that uses other parameters such asquantity of cement admixtures coarse aggregate shyne ag-gregate and water were not able to perform well in pre-diction of tensile and exural properties [53] this limitationwas overcome by the current model where both the MRAand ANN model performs well with the given factors usboth current models can predict the complete mechanicalbehavior of shyber admixed concrete with high precision

4 Conclusion

is study investigated the feasibility of modeling a pre-dictive analysis through earlier study data converting theunstructured factors to possible structured parameters andusing those in creating the MRA model and ANN modelAlso the eectiveness of these models is tested using sta-tistical tools such as R2 and RMSEe compressive strengthmodel shows that ANN has ecient prediction model withR2 value in unity e MRA model has R2 value of 093 butthe error dierence is 723MPa which is very high for apredictive model e MRA model of split tensile strengthand exural strength shows high eciency even though theR2 values are lesser than the compressive model the per-formance of models is relatively strong e ANN model for

split tensile and exural strength has similar statisticalvaluation e MRA model shows more robustness whilepredicting the exural strength than the split tensilestrength Also it is noted that the MRAmodel performs wellin split tensile and exural strength prediction and is vali-dated through the R2 and RMSE values e MRA performswell similar to that of ANN and achieves half its eective-ness except in compressive strength prediction e studyconcludes that the shyber properties contribute high to theprediction model thus increasing the modelsrsquo performance

network (ANN) e fiber properties were used as param-eters along with basic concrete and fiber parameters withsingle target system and the model is tested through sta-tistical tools for its performance

2 Prediction Modeling and Testing

e model created here is for fiber-reinforced concrete thedata set was collected for steel fiber polypropylene fiberhybrid fiber glass fiber and basalt fiber from early studiese actual compressive strength split tensile strength andflexural strength are taken as the target values based on thefollowing parameters which are used as input parameters

(1) Tensile strength of fiber (F)(2) Percentage of fiber (P)(3) Watercement ratio (R)(4) Cross-sectional area of test specimen (A)(5) Youngrsquos modulus of fiber (Y)(6) Mechanical strength of control specimen (S)

Based on the input parameter and target values theoutput was generated through ANN and MRA and theseoutput values were compared with target (actual) values etypes of fibers and its respective literature source are pre-sented in Table 1e active compressive strength data set has5 columns and 252 rows (5times 252) of input data and 1 columnand 252 rows (1times 252) of target data e active split tensilestrength data set has 5 columns and 119 rows (5times119) ofinput data and 1 column and 119 rows (1times 119) of target datae active flexural strength data set has 5 columns and 150rows (5times150) of input data and 1 column and 150 rows(1times 150) of target data e target data for compressivestrength split tensile strength and flexural strength were usedin both the MRA and ANN model as separate target in thisstudy is single target system was used due to the usage ofcross-sectional area of test specimens as one of the param-eters and it was known that the shape of the specimens varieswith different mechanical strengths

21 Prediction Model and Its Statistical Test Two predictionmodels artificial neural network (ANN) and multiple re-gression analysis (MRA) are used in this study to predict thecompressive strength split tensile strength and flexuralstrength of fiber-reinforced concrete (FRC)

22 Artificial Neural Network (ANN) e ANN predictionmodel is programmed through MATLAB with two hiddenlayers 15 neurons in each hidden layer and one output layerwith dependent variable as compressive strength split ten-sile strength and flexural strength Among all the data ap-proximately 70 15 and 15 has been considered fortraining testing and validation respectively e LevenbergndashMarquardt (LM) algorithm is used for training due to itsrobustness and speed Layered feed-forward networks havebeen used in this algorithm in which the neurons are arrangedin layers Here signals are sent forward and errors arepropagated backwards

23 Multiple Regression Analysis (MRA) In this study thelinear-type multiple regression analysis modeling is carriedout using MS excel e coefficients of regression are cal-culated by considering 95 confidence level hence the errortolerance level is limited to maximum of 5 For a giveninput variable the calculated probability value (p value)is considered to be significant if and only if its value is lessthan 005 rough the regression analysis the followingcoefficients presented in Table 2 were found and substitutedin linear multiple regression equation (equation (1))

output I + C1F + C2P + C3R + C4A + C5Y + C6S (1)

24 Statistical Test e performance of the ANN and MRAprediction for the mechanical behavior was tested throughthe statistical methods e tests involved are coefficient ofdetermination (R2) and root mean squared error (RMSE)e coefficient of determination is presented in equation (2)is can be obtained from the comparative chart of pre-dicted compressive strength vs experimental compressivestrength e accuracy of the predictions of a network wasquantified by the root of the mean squared error difference(RMSE) between the experimented and the predictedvalues and the procedure of finding RMSE is presented inequation (3)

3 Results and Discussion

e effectiveness and the acceptance of prediction modelsare based upon the ability of the model to predict the outputIn this study the models were designed to predict themechanical behavior (mechanical strength) of FRC based oninput parameters and two methods of predictions ANNand MRA are used e prediction models are validatedthrough coefficient of determination (R2) and root meansquared error (RMSE) and are consolidated in Table 3

e MRA and ANN prediction of the compressivestrength value is plotted with respect to the actual compressivestrength and presented in Figures 1 and 2 respectively eMRA prediction has the coefficient of determination R2 as093 which is almost an acceptable value whereas the ANNhas an R2 value of 1 which indicates that the ANN model isaccurate e RMSE of the MRA model is 723MPa and theANNmodel is 014MPa which demonstrates that error in theMRA model is large and cannot be relied upon for predictingthe compressive strength

e MRA and ANN prediction model plot for splittensile strength with respect to its actual value is presented inFigures 3 and 4 respectively e R2 value for the MRAmodel is 087 and ANN model is 094 e RMSE for the

exural strength was also of higher accuracy ough theshybers have various factors on inuencing the strength de-velopment in concrete the prediction models MRA andANN are accurate by its output values e ANN eventhough has its advantage of higher accuracy over MRAmodel the performance of the MRA model is also eciente contribution of shyber properties in the prediction modelproved to be eective and also gives more preciseness to themodel Earlier models that uses other parameters such asquantity of cement admixtures coarse aggregate shyne ag-gregate and water were not able to perform well in pre-diction of tensile and exural properties [53] this limitationwas overcome by the current model where both the MRAand ANN model performs well with the given factors usboth current models can predict the complete mechanicalbehavior of shyber admixed concrete with high precision

4 Conclusion

is study investigated the feasibility of modeling a pre-dictive analysis through earlier study data converting theunstructured factors to possible structured parameters andusing those in creating the MRA model and ANN modelAlso the eectiveness of these models is tested using sta-tistical tools such as R2 and RMSEe compressive strengthmodel shows that ANN has ecient prediction model withR2 value in unity e MRA model has R2 value of 093 butthe error dierence is 723MPa which is very high for apredictive model e MRA model of split tensile strengthand exural strength shows high eciency even though theR2 values are lesser than the compressive model the per-formance of models is relatively strong e ANN model for

split tensile and exural strength has similar statisticalvaluation e MRA model shows more robustness whilepredicting the exural strength than the split tensilestrength Also it is noted that the MRAmodel performs wellin split tensile and exural strength prediction and is vali-dated through the R2 and RMSE values e MRA performswell similar to that of ANN and achieves half its eective-ness except in compressive strength prediction e studyconcludes that the shyber properties contribute high to theprediction model thus increasing the modelsrsquo performance

MRA model is 070MPa and ANN is 042MPA e sta-tistical validation of the split tensile strength model showsthat both the MRA model and ANNmodel are in acceptablelimit even though ANN shows more accuracy than MRAthe mathematical model is also predicting the split tensilestrength in par with the ANN model From Figure 3 it isobserved that the MRA model predicts to a high accuracyuntil actual split tensile strength is 4MPa after which the

scatter plots were deviating from the actual trend line FromFigure 4 it is observed that the ANN prediction is accurateuntil the actual strength is 75MPa after which the scatteredplot almost does not shyt the trend line

e MRA and ANN prediction model plot for exuralstrength with respect to its actual value is presented inFigures 5 and 6 respectively e R2 value for MRA andANN was 092 and 094 respectively which has similarvalidation value e RMSE value of the MRA model is099MPa and ANN model is 079MPa Both the MRA andANN were having similar model behavior in terms of sta-tistical validation and graphical representation throughFigures 5 and 6 e prediction is accurate in both MRA andANN models until the actual exural strength is 9MPa afterwhich the scattered plot is observed for both models Butthere were shytted plots for the MRA model at higher actualexural strength which lies between 13MPa and 14MPais higher-order exural strength shytness towards the trendline was not observed in the ANN model e observationindicates that exural strength prediction using MRA andANN model has eectiveness and more accurate predictionis rendered in both models rough the three strengthaspects it was observed that the MRA gains its accuratenessin predicting split tensile and exural strength e ANNpredicts compressive strength to the maximum possibleaccuracy and the prediction of split tensile strength and

exural strength was also of higher accuracy ough theshybers have various factors on inuencing the strength de-velopment in concrete the prediction models MRA andANN are accurate by its output values e ANN eventhough has its advantage of higher accuracy over MRAmodel the performance of the MRA model is also eciente contribution of shyber properties in the prediction modelproved to be eective and also gives more preciseness to themodel Earlier models that uses other parameters such asquantity of cement admixtures coarse aggregate shyne ag-gregate and water were not able to perform well in pre-diction of tensile and exural properties [53] this limitationwas overcome by the current model where both the MRAand ANN model performs well with the given factors usboth current models can predict the complete mechanicalbehavior of shyber admixed concrete with high precision

4 Conclusion

is study investigated the feasibility of modeling a pre-dictive analysis through earlier study data converting theunstructured factors to possible structured parameters andusing those in creating the MRA model and ANN modelAlso the eectiveness of these models is tested using sta-tistical tools such as R2 and RMSEe compressive strengthmodel shows that ANN has ecient prediction model withR2 value in unity e MRA model has R2 value of 093 butthe error dierence is 723MPa which is very high for apredictive model e MRA model of split tensile strengthand exural strength shows high eciency even though theR2 values are lesser than the compressive model the per-formance of models is relatively strong e ANN model for

split tensile and exural strength has similar statisticalvaluation e MRA model shows more robustness whilepredicting the exural strength than the split tensilestrength Also it is noted that the MRAmodel performs wellin split tensile and exural strength prediction and is vali-dated through the R2 and RMSE values e MRA performswell similar to that of ANN and achieves half its eective-ness except in compressive strength prediction e studyconcludes that the shyber properties contribute high to theprediction model thus increasing the modelsrsquo performance

exural strength was also of higher accuracy ough theshybers have various factors on inuencing the strength de-velopment in concrete the prediction models MRA andANN are accurate by its output values e ANN eventhough has its advantage of higher accuracy over MRAmodel the performance of the MRA model is also eciente contribution of shyber properties in the prediction modelproved to be eective and also gives more preciseness to themodel Earlier models that uses other parameters such asquantity of cement admixtures coarse aggregate shyne ag-gregate and water were not able to perform well in pre-diction of tensile and exural properties [53] this limitationwas overcome by the current model where both the MRAand ANN model performs well with the given factors usboth current models can predict the complete mechanicalbehavior of shyber admixed concrete with high precision

4 Conclusion

is study investigated the feasibility of modeling a pre-dictive analysis through earlier study data converting theunstructured factors to possible structured parameters andusing those in creating the MRA model and ANN modelAlso the eectiveness of these models is tested using sta-tistical tools such as R2 and RMSEe compressive strengthmodel shows that ANN has ecient prediction model withR2 value in unity e MRA model has R2 value of 093 butthe error dierence is 723MPa which is very high for apredictive model e MRA model of split tensile strengthand exural strength shows high eciency even though theR2 values are lesser than the compressive model the per-formance of models is relatively strong e ANN model for

split tensile and exural strength has similar statisticalvaluation e MRA model shows more robustness whilepredicting the exural strength than the split tensilestrength Also it is noted that the MRAmodel performs wellin split tensile and exural strength prediction and is vali-dated through the R2 and RMSE values e MRA performswell similar to that of ANN and achieves half its eective-ness except in compressive strength prediction e studyconcludes that the shyber properties contribute high to theprediction model thus increasing the modelsrsquo performance
