钢框架梁抗火分析有限元模型的建立

Finite element model building for fire resistance analysis of steel frame beam

介绍了应用有限元法进行钢框架梁抗火设计研究时有限元模型的建立,简述了所研究问题的必要性,总结出将工字钢上下翼缘及中间腹板的实际温度加到模型中去的技巧。

The finite element model building for fire resistance analysis of steel frame beam is introduced. The skills simulating true stress states of steel frame beam in fire resistance analysis and adding the true temperatures of wings and web plate of I beam to model are described.
