In order to study the seismic behavior of specially shaped reinforced concrete (RC) columns, thirteen specimens were tested under low amplitude cyclic load. The variables studied in this program included limb length, axial load ratio, angle of horzontal load and stirrup ratio. Through the test, the load-displacement relationships of the specially shaped RC columns were obtained. By considering the length of plastic hinge, a numerical analysis method based on fiber model was adopted for estimating the nonlinear behavior of specially shaped RC columns, and a computer program was developed to simulate the load-displacement skeleton curves of these columns. Finally, the calculated results were compared with experimental data, and they agreed well with each other. The method was convenient for predicting the nonlinear behavior of specially shaped RC columns in earthquake.
