| 摘 要： | 为了进一步探讨复杂加载路径下钢筋混凝土L形柱的受力性能,采用基于有限单元柔度法纤维模型梁柱单元,对忽略剪切和扭转影响的钢筋混凝土L形柱在不同加载路径下的抗震性能进行了计算机模拟分析,研究了不同加载路径对钢筋混凝土L形柱承载力、延性、累积滞回耗能等的影响。结果表明,现有钢筋混凝土L形柱抗震性能评定方法应作适当调整,以考虑加载路径对评定结果的影响。

| Abstract: | To probe further into seismic behavior of L-shaped reinforced concrete columns under complex load paths,L-shaped reinforced concrete columns without considering the effects of shear and torsion are analyzed under different load paths by using the fiber-model beam-column element on the basis of the finite element flexibility method.The effects of different load paths on the strength,the ductility and the cumulative hysteretic energy dissipation of L-shaped reinforced concrete columns are studied.The results show that the existing method for estimating the seismic behavior of L-shaped reinforced concrete columns should be relevantly adjusted to consider the effects of load paths. |
