大跨度预应力结构体系等代框架计算模型研究
Study on Equivalent Frame Model for Largespan Prestressed Concrete Residential Structure System
【摘要】 对等代异形柱框架模型分析大跨度预应力住宅结构体系的相关问题进行了研究。分别采用纤维模型梁柱单元和壳单元模型对大跨度预应力结构在竖向和水平作用下的受力性能进行了大量的对比分析,并同大型结构试验结果进行了对比,确定了等代框架模型的参数。结果表明,等代框架计算模型是可行的,尤其是对于非线性分析,具有较高的分析效率和精度。
【Abstract】 In this paper,a study is carried out on large-span prestressed concrete structure system in residence analyzed by specially-shape column equivalent frame model.Applying fiber model column-beam element and shell element,a large amount of comparative analyses about large-span prestressd concrete structure under horizontal and vertical load is carried out.The parameter of the equivalent frame is confirmed based on comparison with the result of the man-sized structural experiment.It is proved that the equivalent frame model has high efficiency and precision especially for nonlinear analysis.
