基于SAP模型的预制装配式钢筋混凝土框架结构的推覆分析
|
摘要
为了研究预制装配式钢筋混凝土框架结构的地震响应,本文根据欧洲研究课题组在最新的实验研究中所采用的往复加载试验模型,利用SAP2000结构分析软件建立数值模型对结构进行推覆分析。结构中的柱子构件在地震力的作用下将产生非线性变形,这种非线性变形的特性是由塑性铰和非线性连接来实现的。本文对于塑性铰与非线性连接的材料属性的评估过程也进行了详细的论述。推覆分析结果与往复试验数据的比较表明,本文提出的推覆分析模型可以较好地模拟预制框架结构的受力和变形过程,对结构的抗震性能有较准确的预测,为数值模型进行结构抗震性能分析提供了依据。
In order to study the seismic responses of precast RC frame structures,the pushover analysis was carried out on the basis of SAP2000 model built according to the test prototypes for cyclic loading tests by European Research Group.In the numerical models,plastic hinge and nonlinear link were used to simulate the nonlinear behavior of the columns subjected to seismic load.From the comparison between numerical results and experimental evidences of cyclic loading tests,it can be found that the presented SAP model can accurately simulate the loading and deformation of the structure,predict the seismic performance of the structure,and promote the application of the numerical model in the seismic analysis of structures.
