Due to the lack of deformability of R/C short columns, it is very important to treat strength and deformation simultineously in analytical study. In this paper, Direct Compression Field and Indirect Compression Field (Truss) are used to simulate the shear resistant mechanism of R/C short columns. Firstly, a lower bound analysis is performed, and the variation of shear resistant mechanism as well as the stress conditions of the columns are discussed. Then, a macro-model is developed by Equivalent Axial Strength methods, and comparison is carried out with the lower bound analysis. By taking account of flexure resistance properly into the above macro-model, a macro analytical model is constructed for R/C columns subjected to combined bending, shear and compression force. Using the above macro-model, strength surfaces of R/C columns are obtained, and through deformation analysis, the elastoplastic deformation behaviors and failure modes of R/C columns are clarified.
