摘　　要：文章论述了某山地住宅的高层结构体系、主要设计参数和结构超限情况,并提出了抗震性能化的设计目标。针对结构超限状况,本工程进行了多遇地震作用下(小震)弹性分析(包括振型分解反应谱法和弹性时程分析法)、设防地震作用下(中震)的等效弹性分析、罕遇地震作用下(大震)的等效弹性与弹塑性时程分析。本工程还补充了中震和大震作用下的楼板应力分析。通过进行各项分析验算,保障了超限结构的抗震性能。This paper introduces the high-rise structural system,main design parameters and structural overrun of a mountain residence,and proposes the design goal of seismic performance.In view of the structural overrun condition,this paper has carried out elastic analysis under frequent earthquakes(including mode decomposition response spectrum method and elastic time history analysis method),equivalent elastic analysis under inter-mediate earthquakes,and equivalent elastic and elastic-plastic temporal analysis under rare earthquake.This paper also complements the floor slab stress analysis under moderate and large earthquakes.Through various analyses and calculations,the seismic performance of the out-of-limit structure is guaranteed.
