摘　　要：如何从定性到定量评价研究建筑结构抗震能力,尤其是量大面广的农村民居的抗震能力是一个重要而又棘手的问题。该文对12组墙片进行拟静力试验,得到了墙片的滞回曲线、骨架曲线和破坏状态,墙片的骨架曲线和破坏状态进行对比,按照对应的剪应力和位移角进行破坏等级划分,得到了农居主要承重构件墙片的破坏等级双参数定量划分方法。对五大类农居进行了6度~10度的震害矩阵完善,在农居震害矩阵的基础上提出了易损性指数计算新方法,解决了震害矩阵之间的评价问题。How to evaluate the seismic capacity of building structures qualitatively and quantitatively is still an important and difficult problem, especially for buildings in rural areas. This study separates rural buildings into five categories based on a large number of on-site investigation of buildings and the seismic damage grade division in China, which can be used as a guidance for the classification of the damage levels of rural and civil buildings in earthquake areas. Based on the pseudo static test on 12 sets of masonry wall panels, a new method for the quantitative classification of the damage level of major components in rural buildings is established. A vulnerability index calculation method is proposed based on the earthquake damage matrix of rural buildings, and the seismic damage matrix of five typical rural buildings is settled. The seismic damage matrix and damage estimation methods are formally united.
