[提要] 在用試驗驗證有限元計算精度的基礎上,對鋼框架梁柱栓焊節(jié)點的滯回性能進行了有限元分析,得到了連接處梁端截面應力分布,揭示了梁翼緣發(fā)生脆斷的原因,指出了現(xiàn)行規(guī)范設計方法的不足之處及對此問題的展望。
[關鍵詞] 鋼框架 梁柱節(jié)點 對接焊縫 有限元模型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.
Keywords: steel frames; beam-column connections; butt welding; finite element model
