摘要
钢框架中梁柱构件的转动约束刚度是重要的参数。它在钢框架构件耐火极限计算及抗火设计中有很重要的应用。以一个典型4跨6层纯框架为例,用有限元方法计算了该框架结构所有梁柱构件的转动约束刚度,并且对各种约束刚度的影响因素进行了分析。
The rotational restraint stiffness of beams and columns in frame structure is a very important parameter.In calculating the frame member＇s fire resistance and anti fire design,this parameter is of vital importance.This paper used the FEM to calculate the rotational restraint stiffness of every beam and column in a typical 4 bay 6 story frames,and analyzed the factors that influence this parameter.
