[提要]  采用有限單元法對(duì)有吊車的單跨和雙跨半剛接門式剛架進(jìn)行了研究，分析中考慮了端板連接節(jié)點(diǎn)的半剛性和構(gòu)件的幾何非線性，探討了節(jié)點(diǎn)半剛性對(duì)門式剛架內(nèi)力和位移的影響，并給出了設(shè)計(jì)建議。
[關(guān)鍵詞]  半剛性  端板連接  門式剛架  內(nèi)力  位移

One-bay and two-bay semi-rigid portal frames with crane are analyzed with finite element method, and the effects of connection's flexibility and members' geometrlc nonlinearity are considered. Internal forces and deformations of portal frame with different rotational stiffness are discussed. Design method are presented in design practice.
Keywords:  semi-rigid; end-plate connection; portal frame; internal force; displacement
