摘要
温度升温作用作为结构设计的必要考虑因素,对钢结构的影响是不可以忽略的,通过有限元模拟软件对结构升温进行相关模拟及分析,以Q235钢的屈服强度为界限,通过改变温度及温度作用的时间,来定义Q235钢的温度骤然升温公式,并且进行相应的解析,通过实例验证,证明有限元分析的可行性。为将来钢构件在炎热地区设计,提供这方面的基础资料。
As a necessary consideration in structural design,the effect of temperature rise on steel structure can not be ignored.The temperature rise of the structure was simulated and analyzed by finite element simulation software.Taking the yield strength of Q235 steel as the limit,the formula of sudden temperature rise of Q235 steel is defined by changing the temperature and the time of temperature action,and the corresponding analysis is carried out.The feasibility of finite element analysis is verified by an example.This paper provides basic data for the design of steel members in hot areas in the future.
