基于FAHP和中心点三角白化权函数的区域砖混结构农居抗震性能评价

Seismic performance evaluation for regional rural houses of brick structure based on FAHP and central point TWW function

本文在引入模糊层次分析法(FAHP)和中心点三角白化权函数灰色评估模型的基础上,结合项目(国家地震社会服务工程-农居震害评价系统)建立区域砖混结构农居抗震性能评价指标体系,其中指标权重用FAHP法来确定,各指标的实际值根据项目实地调查数据确定,再结合FAHP和中心点三角白化权函数进行综合评价,确定所属灰类。最后将方法运用于区域A(西南地区)和区域B(东北地区)的砖混结构农居抗震性能评价,验证了该方法的可行性。又结合区域A、B实际震害结果,验证了方法的有效性。此法为以后农居抗震防灾工作的开展提供一定的参考。

In this paper,based on the FAHP method and central point triangle whiten weight（ TWW） function-the gray assessment,the seismic performance evaluation system for the regional rural houses of brick structure is established. The index weight is determined by FAHP,and the actual value of each index is determined by the field survey data. Then FAHP and central point TWW function are comprehensively assessed. Finally,the method is applied to the seismic performance evaluation of rural houses of brick structure in area A and area B,and the method is proved feasible. Then we combine the actual damage results in areas A,B to demonstrate the effectiveness of the method. This provides a reference for the work on seismic resistance of rural houses in the future.
