The effect of biaxial bending-shear force reversals and varying axial load on the shear resisting behavior of short reinforced concrete columns was experimentally investigated. The short columns with square section were cyclically deflected along their principal axes and their diagonals to produce biaxial bending-shear under uniaxial loadings. The results from 10 tests were considered. It was concluded that the shear strength of short columns under varying axial load could be estimated using existing existing empirical formulae and, in case of high axial stress, the shear strength of column loaded diagonally was 5~6 % lower than that of the column loaded along the principal axis
