巨型框架-次框桁架结构抗震性能分析
|
摘要
提出了巨型框架—次框桁架结构体系。采用ANSYS有限元程序对巨型框架—次框桁架结构体系进行了抗震动力时程分析,讨论了该结构体系在多条地震波作用下的动力位移及内力等地震响应。计算结果表明,巨型框架—次框桁架结构体系具有良好的抗震性能,能够提高巨型框架结构的抗震性能,不但可以有效地降低结构构件的地震内力,同时也不会给主框架结构体系的布置带来较大的影响,巨型框架—次框桁架结构是一种抗震性能良好的结构体系。计算结果对巨型结构的抗震设计有较大的参考价值。
In the article a new mega-frame-sub-truss-frame system is developed.By means of the ANSYS finite element program,the earthquake resistant behavior and earthquake responses of the mega-frame sub-truss-frame system are analysed,such as dynamical displacement,internal force response,etc.The results are shown that mega-frame sub-truss-frame system has the good earthquake resistant performance.The earthquake resistant performance of the system can be enhanced,the internal force response of the structure can be reduced,and at the same time,the arrangement of main-frame system has not been influenced seriously.The mega-frame-sub-truss-frame system is one kind of good earthquake resistant structure system.The calculated results have an important referential value to the earthquake resistant design of megaframe.
