由节点的变形协调和力的平衡条件,本文导出了考虑梁柱节点域剪切变形的钢框架结构分析方法。所得的方法只需对常用的框架计算方法适当地作些修正即可,且易于编制电算程序。同时,通过大量的对比计算分析,提出了不用考虑节点域剪切变形的划分条件,并对需要考虑节点域剪切变形的钢框架提出了实用的修正公式,以方便工程设计。
From the deformation coordination and force balance conditions of the node, this paper derives the analysis method of the steel frame structure considering the shear deformation of the beam-column joint domain. The obtained method only needs to make some modifications to the commonly used framework calculation methods, and it is easy to compile the computer program. At the same time, through a large number of comparative calculations and analysis, a division condition without considering the shear deformation of the node domain is proposed, and a practical correction formula is proposed for the steel frame that needs to consider the shear deformation of the node domain to facilitate the engineering design.
