摘要
在回顾梁柱节点试验的基础上 ,通过对节点的有限元分析 ,验证了按照现行规范设计的刚性梁柱节点发生脆断的可能性 ,得出了连接处梁端截面应力分布及梁翼缘发生脆断的原因 ,提出了改进节点及加强措施 。
By retrospection of tests on beamcolumn connections and analysis on the result of the finite element model, after verifying the ability of fracture of rigid beamcolumn connections that are designed based on the current specifications, this article gets the distribution of stress in section of beam near the connection and gives out a modified joint. At last, the authors point out the errors in current specifications and the future work about this problem.
