| Abstract: | 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. |
