火灾条件下钢结构材料的力学性能研究

Studies of steel structure material mechanical performance under the fire condition

通过万能材料试验机 ,对建筑中常用的Q2 35钢在火灾条件下的力学性能进行了研究 ,获得了Q2 35钢的屈服强度、极限强度、弹性模量、极限应变等力学性能指标随火灾温度变化的规律 ,并对影响Q2

The Q235 steel’s law of the performance index of such mechanics as yielding strength, limiting strength, elastic mould and limiting stain, which change with fire temperature, was gained by studying the mechanical performance index of Q235 steel commonly used in construction under the fire condition on a universal material testing machine, and the influencing factors of Q235 steel’s mechanical performance index were analyzed.
