Shear Transfer Model for Reinforced Concrete

A functional model is constructed for the shear stiffness of cracks in reinforced concrete under monotonic and cyclic loading. The model is in satisfactory qualitative agreement with the available experimental results and it incorporates more parameters than those, the effects of which have been studied by testing. Therefore it provides guidance for future experimental investigations in studying the effect of significant parameters. Supplemented by test results and by the help of a statistical analysis the functional model is turned into a simple predictive monotonic model that can be used both for refined finite element analysis and for establishing a basis for improved design methods for reinforced concrete.
