| 摘 要： | 为了对受火灾影响钢结构厂房进行安全性评估,对火灾后相邻倒塌厂房进行了材料性能试验研究,结果表明,目前火灾后钢材残余强度的计算方法有较大误差,现场检测可以根据钢材表面特征定性判断材料强度损失,但要精确估计火灾后钢材的残余强度宜进行材料试验。另外,高强螺栓连接性能应引起评估人员关注。检测试验结果及安全性评估结论可供类似工程参考。

| Abstract: | For the purpose of assessing the safety of a steel mill building after fire,the mechanical behavior of the material of the collapsed part of the structure in fire is studied by testResults show that existing calculation methods can not be used to estimate the residual strength of steel after fire exactlyEven though the strength loss can be judged through the appearance of the steel after fire,it is the best way to estimate the strength of steel after fire by testBesides,behavior of high strength bolts must be taken into account in the safety assessment on steel structures after fireTesting results and assessment conclusions can be used as a references for similar engineering assessment |
