摘要
钢结构耐火性不足一直是制约其发展的重要因素.基于某钢架结构仓库火灾为工程背景,通过调查火灾情况、现场勘验及数据分析,描述了火灾对仓库基础及钢结构构件的影响,并通过力学性能试验及金相分析,确定钢材性能的变化,评估钢结构的安全性等级,为类似工程情况的安全性鉴定提供参考.
Steel structure fire resistance has been an important factor of restricting its development. The steel structure fire resistance has been an important factor of restricting its development. Based on a steel structure warehouse fire as the engineering background,the influence of the steel structures was described through the investigation of fire and scene investigation and data analysis,and based on mechanics performance test and metallographic analysis,the change of steel performance and the safety of steel structure level were evaluated. The study providing the reference for similar projects.
