［提要］加強(qiáng)環(huán)式節(jié)點(diǎn)是常見的鋼結(jié)構(gòu)梁柱節(jié)點(diǎn)連接形式之一。為了滿足建筑功能需要，節(jié)點(diǎn)外接梁的布置變得越來越復(fù)雜。結(jié)合某實(shí)際工程節(jié)點(diǎn)的模型試驗(yàn)，應(yīng)用有限元軟件對(duì)其進(jìn)行數(shù)值分析。利用試驗(yàn)結(jié)果對(duì)有限元模型的實(shí)用性進(jìn)行了校核，得到與實(shí)際相符的有限元模型。通過有限元分析，進(jìn)一步了解到該節(jié)點(diǎn)的受力性能和破壞機(jī)理，其分析結(jié)果可供設(shè)計(jì)參考。

Finite Element Analysis on Steel Beam-column Joint Strengthened by Plate Ring/He Jun(The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010,China)
Abstract: Steel beam-column joint connection strengthened by plate ring is widely used. To meet the requirement of the architecture function, the beam arrangement has become more and more complicated. Numerical analysis is applied with FEM software on the typical joint experiment of one building project. The accuracy of the FEA model is verified and confirmed by comparing with the test result. Based on the analysis, the structural behavior and the collapse mechanism of the joint are further understood. The result can be referred for future design.
