多层建筑超限抗震措施探讨

Discussion on antiseismic measures of multistory buildings

通过对某超限多层建筑结构设计的分析,得出对于超限多层建筑一般需用不少于两种合适的不同力学模型进行计算,并采用时程分析法进行补充分析计算,根据时程分析法结果,得出合理的地震放大系数,以保证结构安全;同时对于薄弱位置进行有针对性的加强。通过以上各种措施,使结构具有良好的抗震性能。

Through the analysis of the design of a certain multi-storey building structure,it is concluded that the abovementioned two types of suitable mechanical models are used for the calculation of the over-limit multi-storey buildings,and the time-history analysis method is used to calculate and analyze. According to the time history analysis results,the seismic amplification coefficient was obtained,to guarantee the safety of the structure; at the same time,the weak position was strengthened. Through the above measures,the structure has good antiseismic performance.
