BRIEF DESCRIPTION OF SOFTWARE
Purpose of software
The ACOBRI software is used for preliminary design of the rolled-steel main beams of a composite steel and concrete bridgesuperstructure. It is intended as a means of checking the feasibility of a design solution, optimizing a preliminary design throughappropriate choice of parameters, and estimating the main quantities involved. It is not intended to produce a construction designcalculation report
Scope of application
The kinds of bridges handled are road bridges, railway bridges, and footbridges with superstructures made made out of steel rolledgirders and a participating reinforced concrete slab or with filler-beam decks. Decks may be simply supported or continuous in thecase of multi-span bridges. Calculations and verifications are performed in accordance with Eurocodes EN and National Annexes.
Method of analysis and design checks
On the basis of a definition of bridge geometry, materials, and loads, the program calculates internal forces and moments in the mainbeams under the effect of: dead load, superimposed dead load and live load; concrete shrinkage; temperature differential; anysupport height adjustment. The analysis is performed with a finite element solver, using a grid model. The structure is discretized bybar elements corresponding to segments of the main beams, longitudinal and transverse strips of slab, and any crossbeams. Forcalculating flexural and torsional stiffnesses, account is taken of creep and any concrete cracking, depending on the type of internalforces or moments. Longitudinal and transverse influence lines are used to determine the position of mobile loads producing extremeeffects at the different cross-sections considered.
To establish preliminary design of beams, the program calculates the main load combinations for the bridge in the in-service phase.The design checks for the serviceability limit state and ultimate limit state concern stresses in the beams and in the longitudinalreinforcement, compressive stresses in the concrete, the ultimate moment resistance, crack control and the vertical deformation and
stress variation in beams at the fatigue limit state. The software also calculates reactions at supports and the number of connectorsrequired to transfer shear forces between the beams and the slab. For filler-beam decks, the calculations include a number of specialfeatures in accordance with the specifications of the design codes.
Detailed information on the scope of application of the software, on the assumptions, methods, and approximations used and on thecalculations performed are provided in the users manual and in the on-line help module.
Comments :
The program can deal with straight, unskewed bridges with a horizontal slab of constant thickness. If the bridge to be analyzed doesnot match these assumptions but does not vary substantively from them, the software can be used for an approximate calculation. Inthis case the user will have to use engineering judgment both to determine the adaptations to be made to the data entered and toassess the representativity of results given and, as required, adjust or complete the calculations and checks.
The software establishes a preliminary design for the main beams of the bridge under in-service conditions. It does not carry out any
checks for construction phases. Lateral-torsional buckling of beams is not analyzed for the construction phase. Diaphragms and/orbracing may have to be implemented for the construction phase as well as the in-service phase.
ACOBRI is a preliminary design software tool which does not analyze all situations or perform in an exhaustive manner all theverification calculations required for construction design.
ACOBRI was developed by CTICM, Centre Technique Industriel de la Construction Métallique, France.

SUMMARY OF RESULTS
Criterion : Deflections at track center line (Serviceability Limit State)
Max. ratio = 0.97 < 1.00 SATISFACTORY
Lane/Track No.-1 - Cross-section No.7 : Position = 3.50 m
Position of the plastic neutral axis
All plastic neutral axes are in steel sections.
Checking minimum reinforcement criterion
Reference : EN 1994-2:2005 7.4.2Slab reinforcement ratio : 1.00 %
The criterion is satisfied for all design cross-sections, for 20 mm diameter bars.
