地震结构易损性模型是灾害风险评估的重要组成部分,而在目前的中国,随着城市化进程的加剧,目前建成了数量庞大的高层、超高层建筑,但却缺少专门适用于高层建筑的易损性模型。研究通过对已有高层、超高层建筑抗震分析资料及其他基本信息进行统计汇总和分析计算,并利用统计学方法对所得数据进行处理,以最大层间位移角作为目标结构需求,研究了基于谱位移(Sd)的结构地震易损性。根据不同的设防标准和不同的性能水平,建立了相应的曲线,并综合考虑了结构的高度、场地等相关因素的影响。研究获得的系列易损性曲线可以对不同强度地震作用下的高层、超高层结构损害进行有效的评估,并为地震灾害评估提供有价值的参考。
Seismic structural vulnerability model is an important part of disaster risk assessment. In China, with the urbanization progressing rapidly, a large number of high-rise and super-high-rise buildings have been built at present, but there is a lack of specialized methods for high-rise buildings Vulnerability model. Based on the summary and analysis of the seismic data and other basic information of the existing high-rise and super-tall buildings, the data are processed by using statistical methods. The maximum interlayer displacement angle is taken as the target structure requirement. Displacement (Sd) Structural Seismic Vulnerability. According to different fortification standards and different performance levels, the corresponding curves are established, and the influence of the factors such as the height of the structure, the site and so on are comprehensively considered. The series of vulnerability curves obtained from this study can effectively evaluate the structural damage of high-rise and super-tall buildings under different intensity earthquakes and provide valuable reference for the earthquake disaster assessment.
