The main purpose of this study is to clarify the shear failure properties of RC short columns by the finite element method taking into consideration of experimental results. For column specimens with fixed ends, the sectional area is 25cm x 25cm, the length is 75cm and the ratio of shear span to depth is 1.5. As experimental and analytical parameters, axial load, circumferential length of tensile steels and bond condition are used. For analytical study, cracking in concrete is modeled by the discrete cracking model. In the experimental study, spacing of flexural cracks and the effects of axial load, circumferential length of tensile steels and bond condition for flexural cracks and flexure - shear cracks in the end portions are discussed. In the analytical study, the effects of axial load, circumferential length of tensile steels and bond condition on the shear failure properties of RC short columns are discussed.
