摘要
通过对已有试验结果的分析、公式推导和节点参数计算,指出影响端板连接节点刚度的关键因素是节点域刚度,提高节点刚度最有效的措施是提高节点域刚度.提出薄柔钢框架中刚性端板连接节点的设计方法,根据薄柔构件的特点,在现行规范基础上对节点组件的设计作了修改和补充,对节点增加了刚度计算和刚性判断.当初步设计的节点不满足刚接要求时,提出了加厚节点域柱腹板的调整措施.按照此方法设计的端板连接节点可以被认为是刚性节点.
It was indicated by the analysis of experimental result available,formula derivation,and computation of joint parameters that the stiffness of joint in end-plate connection was mainly affected by panel zone stiffness,and the most effective measure to improve the joint stiffness would be to improve the panel zone stiffness.The method to design rigid joint in end-plate connection for slender flexible steel frames was then put forward.According to the characteristics of slender flexible members,design methods of joint components were partly modified or supplemented based on current codes.Both stiffness calculation and rigidity estimation were performed for joint design.If the joint preliminarily designed could not fulfill rigid requirement,the measure of thickening column web in panel zone would be recommended.Designed with this method,the joint could be regarded as rigid one.
