摘　　要：采用基于有限单元柔度法的纤维模型梁柱单元对不同轴压比的钢筋混凝土异形柱在不同加载方向下的受力性能进行模拟分析,并分别从承载力、刚度及延性3个方面进行比较,从而为异形柱的受力性能分析及抗震设计提供参考依据.结果表明,L形和T形柱在不同方向上的承载力、刚度及延性相差较大,而十形柱在不同方向上的承载力、刚度及延性则比较接近.With fiber beam-column element based on flexibility method of finite element, the RC specially shaped columns of different axial compression ratio under cyclic loading have been simulated and the analysis results have been compared in aspects of strength, stiffness and ductility in order to provide some suggestions for seismic-resistant design of specially shaped columns. The strength, stiffness and ductility of L,T-shaped columns are apparently different in different horizontal direction, but those of t-shaped column are close.
