高温工况钢结构的设计计算

DESIGN CALCULATION ON STEEL STRUCTURE PART WORKING AT HIGH TEMPERATURE

对高温工况下钢结构以弹性变形与蠕变理论进行设计计算作了实例比较 ,结果表明 :对超过蠕变温度的构件应按蠕变理论计算 ;对低于蠕变温度工作的构件则应按规范的弹性理论计算。

In design calculation on steel structure part working at high temperature, design calculation with creep theory was compared to design calculation with elastic deformation theory. Results showed that design of steel structure part working at creep temperature up must be calculated with creep theory, design of steel structure part working at creep temperature down must be calculated with elastic deformation theory.
