Summary: | Reinforced concrete slabs are used to provide flat, useful surfaces and commonly appear in floors, roofs and deck of bridge. Many slabs exist in more complex cases that do not meet the constraints of elasticity-based method as a result of shape, support conditions or the presence of openings. Then elasticity-based method is not applicable in the analysis of slab with opening. But limit analysis or plastic analysis is an alternative to treat this problem. So yield line analysis that based on limit analysis has been introduced to analyze the slab with opening.
This project involves analytical study on simply supported rectangular slabs with opening by using yield line analysis based on limit analysis. Yield line analysis is utilized to determine the internal and external work done on slab. By equating internal and external work done, relation between applied loading per unit area and ultimate resisting load can be obtained. The procedures stated above applicable to both cases either for ordinary rectangular slab and rectangular slab with opening. Then the effect on load carrying capacity of slab at different dimensions with varying size of opening can be observed.
For the purpose of time saving and accuracy, MathCAD program has been utilized in this project to assist in obtaining values of load carrying capacity at various ratios of slab and opening dimension. |
