摘要

摘要: 针对大跨度空间钢结构安全状态综合评估问题,以承载力、变形、动力特性和荷载环境为准则层,建立三层次大跨度钢结构监测综合评估指标体系。通过构造准则层和指标层的模糊判断矩阵,得出各类监测指标之间的权重,进而提出结构安全综合评估代表值及其计算方法,并给出了综合评估方法流程。采用提出的综合评估指标体系,对单层网壳静载试验监测和杭州西站屋盖钢结构施工过程进行了评估,验证所提出方法的正确性和有效性,并为同类结构监测的综合评估提供参考。

Abstract: In view of the problem of comprehensive evaluation for the safety state of long-span space steel structures, a three-level comprehensive evaluation index system for monitoring long-span steel structures was established, in which the criterion layer included the bearing capacity, deformation, dynamic characteristics, and load environment. By constructing the fuzzy judgment matrix of criterion layer and index layer, the weights of the monitoring indexes were obtained, and the representative values of the comprehensive evaluation for structural safety and its calculation method were put forward. The comprehensive index system proposed in the paper was used to evaluate the static load test of single-layer reticulated shell and the steel structure roof of Hangzhou West Railway Station during construction. These two engineering examples verified the correctness and effectiveness of the method proposed in the paper and provided a reference for the comprehensive evaluation of similar structural monitoring.
