introduction

Experiencing and understanding skeletal construction is important as it is one of the most widely used structures for building support. Exploring the advantage of each materiald and what is the joints that suitable for the materials are highly recommended as we are require to use recycle materials. The purpose of skeletal construction is to tested by one man with 60 kg to sit on it within 2 minutes to see how strong and stable the strcuture is.

Learning outcomes assessed in this project include: - Apply construction system in design. - Recognize the implication of construction systems in design. - Analyse the issues of strength, stiffness and stability of structures including modes of structural systems, forces, stress and strain and laws of static. forces, stress and strain and laws of static.

The objectives of this project are as follows: - To create an understanding of skeletal structure and its relevant structural components. - To understand how a skeletal structure reacts under loading. - To demonstrate a convincing understanding of how Skeletal Construction works. - - To be able to manipulate Skeletal Construction to solve an oblique Design problem.

idea development

The idea is to understand and determine the material and its properties, different kind of joints and connection used on particularpoint of the shelter to withstand the load force.

load and forces

LIVE LOAD

Load Created by the Weight of the Object:

-Forces of the object’s weight aretransfered to the the bambooseating.

-The forces then distributed along -The forces then distributed along the seating to the base of the structure.

-The forces transfered to the ground from the base of the columns.

DEAD LOAD

Load Created by Structure:

-Weight of the structural beams transfered through the columns to the ground.

-Weight of the seating bamboos transfered through the skeletal transfered through the skeletal base to the ground.

TENSION FORCE

Tension Forces Exerted to the Rattan:

-By the bamboo columns

-By the weight load of the user as the user sits back.

COMPRESSION FORCE

Compression Force Exerted to the bamboo columns:

-From the nylon string pulling all four columns together.

FINAL LOAD TEST

The Intial testing was to test the the compression and tension strength of the structure and also our choice of joints such as interlocking and plug-in/bolt connection. The shelter was able to withstand one of our member that weighing approx.60 kg.

CONCLUSION

Upon completing this project, we have learnt that to built a strong Upon completing this project, we have learnt that to built a strong structure is not about the massing but the skeletal structure. We were able to built a light, portable and strong shelter all from the studies of skeletal structure. We were able to understand of how this project gives us a better understanding of construction system in design and gives us the ability to analyse the structural strength, stability and the load distribution. Also, we were introduced to variety of joints and how they are to be constructed. variety of joints and how they are to be constructed. We strongly believe this project will lead us to a greater advantage in the future when we design a building.
