［摘要］在对134例工业厂房进行实地调研的基础上，汇总分析旧工业厂房存在的结构安全问题，并依据各类工业厂房结构可靠性问题发生的频率进行排序，逐次分析有共通性且频率较高的结构安全问题，提出工业厂房的加固改造应该基于改造后的用途和功能对不同结构部件采取不同的改造方法，在保证结构安全的前提下高效、经济地完成工业厂房的改造。结合实例分析，对旧工业厂房改造前进行结构可靠性检测，基于安全目的对旧工业厂房进行结构加固，能够保证改造工程安全、高效进行，同时能够最大限度地满足改造后建筑的使用功能要求。［关键词］旧工业厂房; 改造; 结构安全; 加固; 功能要求中图分类号：TU745.7 文献标识码：A 文章编号：1002-848X(2016)05-0058-05
Transformation-based structural safety analysis on old industrial plantsWu Qian, Zhang Tegang（School of Civil Engineering, Xi'an University of Architecture and Technology, Xi'an 710055, China）Abstract: Collection and analysis of safety problems for old industrial plant structures were conducted based on field surveys of 134 cases of industrial plants. Sorted by the frequencies of various structural reliability problems for different kinds of industrial plants, sequential analyses were conducted on structural safety problems which had commonality and higher frequencies. Suggestion was proposed that reinforcement and transformation of industrial plants should take different transformation methods in different structural members based on the purposes and functions of the members after the transformation. In the premise of ensuring the structural safety, the industrial plant transformation should be efficient and economic. Combining with the example analysis, the structural reliability tests should be carried out before transformations of old industrial plants, and reinforcement should be taken for the safety purpose to guarantee safety and efficiency of the transformation project and at the same time to meet the service function requirements after the transformation as far as possible.
Keywords:old industrial plant; transformation; structural safety; reinforcement; function requirement
