钢构件在不同温升曲线下的耐火研究

Research on fire resistance of steel components Under different temperature rise curve

快速温升火灾是一种少见但危险极大的火灾情况现在针对这方面的研究还很少,本文通过简化热力耦合效应,建立简单钢构件模型进行数值模拟的方法,研究钢构件在不同温升曲线作用下的力学响应特性。

High-rate heating condition is a seldom but very dangerous event in fire. A nonlinear finite element analysis （FEA） method of basic steel element is introduced by choosing proper material constitutive models for steel beam and pillar.
