N2 - An experimental programme consisting of 8 simply supported deep beams (SSDBs) subjected to unsymmetrical loadings has been carried out. The details of the experimental work and the specimens are briefly presented. Test results including beam crack patterns, load deflection curves and ultimate failure loads are presented. A strut-and-tie model (STM) is used for calculating the shear strengths of the specimens. The model was derived analytically and experimentally verified by the test specimens. It is found that the proposed STM is a generalized form which embodies the special cases of single point and two equal and symmetric point load conditions. The geometry of proposed STM was dependent on the asymmetry of loadings applied, i.e. the load inequality and load asymmetry. Explicit expressions for failure loads of the beams are given in the proposed model.A FEM programWCOMD, developed in Tokyo University since 1980s, was employed to supplement the study based on STM. Generally, the STM predictions are in good agreement with test results and FEM results.
