摘要
文章研究的结构为现代化综合性高层办公楼,由东西向主副塔楼和高位连体结构组成。详细介绍了该结构分析与设计的有关内容,包括高位连体结构连接方式的选择,运用MIDAS/Gen有限元软件建立结构力学三维空间整体模型,进行了主副塔楼结构在多遇地震作用下的地震响应研究、弹性时程分析补充验算,重点介绍通过静力弹塑性(Pushover)分析找出了结构的薄弱部位,并采取相关的抗震加强措施以及连体结构楼板受力分析。分析结果表明,在地震作用下该结构抗震性能良好,能够满足预期的抗震性能目标。
A modern comprehensive high-rise office building is researched,which consists of two towers in the east-west direction and a high connecting structure. The analysis and design of the structure are introduced in detail,including the selection of the connection mode of the high connecting structure. A 3D model of structural mechanics is established by using MIDAS/Gen,and the comparative analysis of structural responses and the elastic time-history analysis for complementary checking computations of the two towers under the condition of frequent earthquake are carried out. The weak parts of the structure are identified by static elasto-plastic Pushover analysis,the relevant seismic strengthening measures are taken,and the floor stress analysis of the connecting structure is made. The analysis results show that the seismic performance of the structure under the action of earthquake is good,and the expected targets of seismic performance are able to be satisfied.
