摘    要:高层隔震结构的分析理论和设计方法是目前隔震技术向高层建筑推广的2个关键理论问题。本文以高烈度区宿迁市已经竣工的高层隔震建筑阳光大厦为工程实例,对高层隔震结构的非线性地震响应分析方法进行了研究,包括隔震支座竖向不同拉压刚度的模拟、各种类型的隔震支座水平力学特性的准确模拟,以及不同地震动输入方式和输入角度对隔震支座受拉情况的影响分析等;在此基础上,对隔震层的设计方法进行了分析,提出了隔震层设计的基本原则,进而给出了控制隔震层设计的基本指标,包括隔震支座的长期面压、极值面压、隔震层偏心率等;最后,对高层隔震结构的相关构造要求进行了必要的说明。

关 键 词:高层隔震建筑  隔震支座力学特性  隔震层设计

Abstract:The analytical theory and design method of high-rise isolated structure are currently two key theoretical issues which are extending the isolation technology to high-rise buildings.In this paper,the analysis method of nonlinear seismic response of high-rise isolated structure was described by a case study of Sunshine Plaza in high seismic intensity region-Suqian City,Jiangsu Province.In addition accurate simulation of horizontal mechanical properties of isolation bearing and influence analysis of different input modes and azimuthes on the bearing were conducted.Based on this,the design method of isolation layer was explained and the basic principles and controlling indices of the isolation layer were presented.At last,necessary remarks were pointed out for related structural requirements of high-rise isolated structures.
Keywords:high-rise isolated building  mechanical properties of isolation bearing  design of isolation layer
