Validation of Sequentially Linear Analysis for Quasi-Brittle Behaviour of Reinforced Concrete Structures under Proportional and Non-Proportional Loading

The aim of this thesis was to objectively and quantitatively assess the accuracy and robustness of two-dimensional sequentially linear analysis (SLA) in comparison to nonlinear finite element analysis (NLFEA), for a range of experiments of reinforced concrete structures with proportional and non-proportional loading schemes. Non-proportional...

Beam or truss mechanism for shear in concrete: Problems converting a beam into a truss

An unpublished study by Prof. A.W. Beeby shows the differences in strength capacity between a reinforced concrete beam without shear reinforcement and the same beam with a cut-out section at the middle of the span. The cut-out section exists at the bottom part of the beam while the reinforcement still remains. It remarkably turns out that the...
