| 摘 要： | 本文对砌体填充墙的损伤状态进行了划分，并将损伤状态与常用修复方案相关联，明确了不同损伤状态所需要的修复方案。为了建立适用于中国砌体填充墙的易损性函数，对砌体填充墙面内抗震性能的试验数据进行了统计分析以建立损伤状态与工程需求参数的拟合经验关系。以层间位移角作为填充墙的工程需求参数，通过对数正态分布拟合试验数据。结果表明采用对数正态分布拟合的易损性曲线能够满足Lilliefors检验要求，可将其用于砌体填充墙的易损性评估中。

| Abstract: | Damage states for masonry infill walls are proposed and linked with commonly employed methods of repair. The repair methods used for different damage states are determined. To develop the fragility functions for masonry infill walls in China, statistic analysis of the results of previous experimental investigations of in-plane seismic performance are performed to generate empirical relationships between damage states and engineering demand parameters. Inter-story drift is accepted as the engineering demand parameter of masonry infill walls and the test data are fitted using a lognormal distribution. The results show that the fragility curves fitted by lognormal distribution can pass the Lilliefors test and can be used in the fragility assessment of masonry infill walls. |
