摘要
黄河口模型试验海域厅A上部结构采用三层网架(局部四层),下部支承结构采用26根钢筋混凝土柱。对其结构体系、受力特点以及荷载取值进行了介绍,对整体结构进行了静力分析、动力分析及抗震分析,研究了整体结构在多遇地震和罕遇地震下的抗震性能。通过分析指出了结构设计的薄弱位置,供类似工程参考。
The upper part of Yellow River Estuary Model Testing Hall A is triple-layer space truss structure(some part is fourfold-layer truss),and the lower part of the supporting system consist of 26 reinforced concrete columns.The structural system,mechanical characteristics and the load of the whole structure are described.Static analysis,dynamic analysis and seismic analysis are carried out.Seismic performance of the structure under frequent and rare earthquake are studied. Through the analysis the weak points of the structure are pointed out,and the result can provide reference for similar projects.
