空斗砖房的震害预测

PREDICTION OF EARTHQUAKE DAMAGE TO THE HOLLOW WALL BRICK BUILDINGS

本文通过对空斗砖房震害的调查和研究,指出影响现有空斗砖房震害的主要因素是房屋的进深、层高和开间宽度,并在此基础上建立了空斗砖房震害预测的模糊综合评判数学模型。在这个模型中,以影响震害的三个主要因素构成模糊综合评判的因素集,应用灰关联分析和二维信息分配原则来确定模糊综合评判中的权向量和单因素评判参数,使给出的震害预测方法兼顾考虑了影响震害的两种不确定性,即模糊性和随机性,因此它不仅简单、方便,而且具有实用价值。

A method of fuzzy synthetical evaluation for the earthquake damage prediction of hollow wall brick buildings is set up in this paper.the factors set of fuzzy synthetical evaluation is formed of the primary factors,which are the depth,height and width of a room,influencing damage of hollow wall brick buildings.The right vector andthe evaluation parameters of one factor of fuzzy synthetical evaluation are obtained by using grey cognate analysis and the prin ciple of two dimensional information distribution. Indetermi nacy of influencing damage,which are fuzzy andd random,have been consid- ered in the damage prediction model so the method is not only simple,convenient and prac- tical but also scientific.
