摘要
在用试验验证有限元计算精度的基础上 ,对钢框架梁柱栓焊节点的滞回性能进行了有限元分析 ,得到了连接处梁端截面应力分布 ,揭示了梁翼缘发生脆断的原因 ,指出了现行规范设计方法的不足之处及对此问题的展望。
By contrast of the results of experiment and the finite element models,after analysing on the results of the finite element models of web-bolted and flange-welded beam-column connections in steel frames,this article gets the distribution of stress in section of beam near the connection and the reasons of fracture of rigid beam-column connections that are designed based on the current specifications.At last,the authors point out the errors in current specifications and the future work about this problem.
