摘要
构件的有限单元模型和合理的滞回曲线模型是框筒结构动力分析的基础。目前对框筒结构中的裙梁研究甚少,至今未见裙梁的滞回曲线模型。本文编制了大型钢筋混凝土有限元程序HOR-CFE,对裙梁进行了大量单调和反复荷载下的有限元计算,得到了裙梁的滞回曲线模型。验证结果表明,单分量模型仍适用于受弯破坏裙梁的动力分析。
Finite element models and reasonable hysteretic loops of members in a structure are the basis of dynamic analysis of the structure.There are few studies of spandrel beams in RC(Reinforce Con- crete)frame-tube and the bysteretic loop model has not been developed up to now.In the paper,span- drel beams under monotonic and cyclic loads are calculated by using FEM.The hysteretic loop of span- drel beams is obtained and the result of verification indicates that the one-component model can be used to the dynamic analysis of spandrel beams yielded due to moments.
