Abstract

There is a pressing need to address the overdesign of reinforced concrete structures. The utilisation of structural concrete members is often very low and structural material wastage in the order of 50% is common. Orr (2011) showed that it is possible to design and build optimised non-prismatic concrete members that use up to 40% less concrete than prismatic members of equivalent strength. Ensuring the safety and reliability of highly efficient structural members requires accurate analysis methods. Predicting the shear behaviour of reinforced concrete members is notoriously difficult and codified design methods are generally based on empirical formulas derived from the testing of prismatic beams. Non-prismatic members fall outside of conventional design codes and current methods for determining their structural response and ultimate limit state behaviour are inadequate. Robust and accurate numerical models are needed for predicting the behaviour of optimised reinforced concrete structural members.
