| 摘 要： | 采用纤维单元模型和实体单元模型对一个钢筋混凝土柱进行了动力弹塑性分析,结果表明,截面纤维模型能以很小的计算成本达到实体单元模型的计算精度,并且和试验结果拟合较好。同时,对一个3层钢筋混凝土框架结构进行的动力弹塑性分析表明,纤维单元模型能很好地解决各种非线性问题,适合于强震作用下结构整体动力弹塑性分析。

| Abstract: | The fiber model and solid element model are established to analyze the dynamic elasto-plastic response of a RC column respectively in this paper. Our results show that the fiber model can simulate the shake table test as accurate as solid element model, and numerical simulation coincides with the experimental results well with a small calculation of cost. Moreover, a reinforced concrete frame is analyzed, and simulation results indicate that the fiber model can solve strong nonlinear problem lightly, which can be used to analyze the structures under strong seismic excitations. |
