| 摘 要： | 为建立适用于砌体结构的加固费用快速估算模型,对中国陕西、山西、四川等地砌体结构建筑物的历史加固费用及相关建筑参数进行统计,建立涵盖35栋砌体结构建筑物加固费用估算模型的回归与验证数据库,同时对影响加固费用的各建筑参数作显著性分析,并基于后向消去的多元线性回归方法,利用SPSS统计分析软件对已采集的加固数据进行回归,得到4个费用估算模型;按照相应评价准则分别对各模型进行评价,提出一套最优的砌体结构加固费用快速估算模型,并对该回归模型进行验证分析。回归得到的费用估算模型满足精度要求,具有一定的工程应用价值。

| Abstract: | In this paper, retrofit costs and relative building parameters of masonry structures in Shaanxi, Shanxi, and Sichuan Provinces were collected, to enable a retrofit cost estimation model for masonry structure buildings to be developed. A regression and validation database, including the retrofit cost estimation models of 35 buildings, was built, and the building parameters which influence retrofit costs analyzed. Then, based on the multiple linear regression method, four models were established using the existing retrofit data with SPSS analysis software. After evaluating the four models according to their corresponding evaluation criteria, an optimal rapid estimation model for the retrofit cost of masonry structures was proposed and verified. The results show that the regression model meets the precision requirements and could be valuable in practical engineering. |
