Shear design should not be regarded as a sectional design process (designers check that the applied shear force does not exceed the shear capacity in vertical sections of a beam). Instead, the design process should look at load transfer in the whole member. This is best done by using strut-and-tie models. In this article, truss models, valid for members with shear reinforcement as well as without, are described. The models are shown to provide very good agreement with test results.
