摘要

场地地震安全性评价是规范对超高层结构设计的强制要求,场地地震反应特性及设计反应谱是超高层结构设计的重要计算依据。本文结合某不规则超高层建筑,讨论了场地地震反应特性及设计反应谱,在对场地进行安全性评价的基础上,比较了天然地震波与设计反应谱的统计误差,不仅证明了设计反应谱的准确性,还为结构抗震验算提供了可靠的天然地震加速度时程波,本文的研究可为同类型超高层结构设计提供经验参考。
Construction ground seismic safety evaluation is the requirement to super high rise building of Code,ground seismic response characteristic and design response spectrum are important data for structural calculation of super high rise building.In this paper,ground seismic response characteristic and design response spectrum were discussed for an irregular shape super high rise building.Based on ground safety evaluation,the statistical errors between the natural seismic records and design response spectrum were compared.The results demonstrated the accuracy of design response spectrum and offered reliable time history record of natural seismic acceleration for structural seismic checking calculation.This research could be a referrence for other similar super high rise buildings.
