【摘要】：近几年来,在一些发达国家,基于概率理论的新一代抗震性能评估方法已开始用于特定建筑物的抗震性能评估。研究基于全概率理论的新一代抗震性能评估方法,并将其应用于我国建筑结构的抗震性能评估,对于减灾防灾和提高建筑结构的抗震性能有重要意义。以FEMA P-58的抗震性能评估流程为框架,结合我国建筑结构的特点和规范要求,以某一单个建筑物为对象,采用有限元分析软件PERFORM 3D和抗震经济性能评估分析软件PACT,用增量动力分析(IDA)方法进行建筑物各个强度状态的易损性分析;用基于强度的性能评估方法,依据构件易损性分组和人员流动模型,得到包括人员伤亡、修复和重建造价以及居住中断时间等建筑性能的概率分布,为我国建筑结构的抗震性能评估提供了参考。
[Abstract]:In recent years, in some developed countries, a new generation of seismic performance evaluation methods based on probability theory have been applied to the seismic performance evaluation of specific buildings. This paper studies a new generation of seismic performance evaluation method based on full probability theory, and applies it to the seismic performance evaluation of building structures in China, which is of great significance for disaster reduction and disaster prevention and for improving the seismic performance of building structures. Taking the seismic performance evaluation flow of FEMA P-58 as the frame, combining the characteristics of the building structure in our country and the requirements of the code, a single building is taken as the object. The finite element analysis software PERFORM 3D and the seismic economic performance evaluation software pact are used to analyze the vulnerability of each strength state of the building, and the strength based performance evaluation method is used. According to the vulnerability grouping and human mobility model, the probability distribution of building performance, including casualties, repair and reconstruction cost and residential interruption time, is obtained, which provides a reference for the seismic performance evaluation of Chinese building structures.
