| 摘 要： | 在13根钢筋混凝土异形柱低周反复荷载试验研究的基础上,采用非线性分析方法对异形柱受力性能进行分析,并编制了计算异形柱荷载-位移骨架曲线的程序,计算结果与试验结果吻合较好,为预测地震作用下的钢筋混凝土异形柱的非线性行为提供了一种便捷的方法.此外,根据程序的计算结果,分析了轴压比、不同柱肢尺寸等因素对异形柱承载力和变形的影响.结果表明:轴压比的增大会提高异形柱的承载力,但试件变形能力有所降低;异形柱腹板尺寸增大时可以有效提高试件的水平极限承载力. |

| Abstract: | 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 compressio... |
| Keywords: | specially-shaped columns nonlinear analysis different lengths of limbs load-displacement skeleton curve |
