摘要:
近年来工程场地地震安全性评价工作日趋规范化,安评相关方法与技术也在不断的发展与完善。而超高、超限等复杂结构类型越来越成为城市建筑建设重点,根据《建筑抗震设计规范》要求,此类建筑在抗震设计工作中需要进行时程分析,时程分析输入地震动的选用需考虑与规范反应谱在“统计意义上相符”。在总结常用选择方法的基础上,提出一种新的选波思路,即按照安评结果反应谱作为目标反应谱,基于强震记录数据库,利用PEER强震记录数据库及搜索平台,寻找最优匹配天然地震波,作为结构时程分析输入地震波,通过实例对比分析,该方法选取的地震波在结构时程分析中具有良好的适用性。
Abstract:
In recent years, the seismic safety evaluation of engineering sites has become increasingly standardized, and safety evaluation methods and technologies have also been developed and improved. Buildings with complex structure types such as ultra-high and over-limit are increasingly becoming the focus of urban construction. According to the requirements of the "Code for Seismic Design of Buildings",time history analysis is required for high rise buildings in seismic design work, and the selection of input ground motion for time history analysis needs to be considered "statistically consistent" with the code response spectrum. Based on the summary of commonly used selection methods, a new wave selection for the input motion idea is proposed, that is, the response spectrum of the safety evaluation result is used as the target response spectrum, the strong earthquake record database,and the PEER strong earthquake record database and the search platform are used to find the best matching natural seismic wave as the input seismic wave for structural time history analysis. Through comparative analysis of examples,the seismic waves selected by this method have good applicability in structural time history analysis.
