摘要：
Based on the experimental study of 13 specially-shaped RC (reinforced concrete) columns under low cyclic load, the method of nonlinear analysis of specially-shaped columns is put forward and the computer program is developed to deal with the load-displacement skeleton curve. The calculated results agree well with the tested data and the method is convenient for predicting the nonlinear behavior of specially-shaped RC columns in earthquake. Furthermore, the influences of design parameters such as axial compression ratio and different length of limbs on bearing capacity and displacement are analyzed. It is shown that the bearing capacity increases and the deformation capacity decreases with increasing of axial compression ratio. Also, the horizontal ultimate load-carrying capacity of specimen is improved greatly when the web length increases.
