［摘要］結(jié)合洛陽龍門鐘樓建筑特點(diǎn)，提出了一種針對(duì)傳統(tǒng)風(fēng)格建筑檐口柱收分的結(jié)構(gòu)構(gòu)造做法，即方鋼管混凝土柱下接鋼筋混凝土柱收分節(jié)點(diǎn)構(gòu)造。通過3種不同的計(jì)算模型分析及整體指標(biāo)對(duì)比，結(jié)果表明方鋼管混凝土柱連接屬性介于鉸接與剛接之間，屬于半剛性連接。結(jié)構(gòu)簡(jiǎn)化計(jì)算時(shí)整體控制指標(biāo)應(yīng)取鉸接、剛接計(jì)算假定的中間值。根據(jù)《鋼管混凝土結(jié)構(gòu)技術(shù)規(guī)范》（GB 50936—2014）相關(guān)要求驗(yàn)算該構(gòu)造下方鋼管混凝土柱在單一受力狀態(tài)和復(fù)雜應(yīng)力狀態(tài)的承載力，結(jié)果表明方鋼管混凝土柱滿足各項(xiàng)受力狀態(tài)下的性能要求。通過整體與局部節(jié)點(diǎn)分析可知，該構(gòu)造節(jié)點(diǎn)安全可靠，可供類似項(xiàng)目設(shè)計(jì)參考。

Abstract:According to building characteristics of  Luoyang Longmen Bell Tower, a structural construction was proposed for cornice column joint of traditional style building, that is  joint structure of concrete-filled square steel tubular  column lower connected with reinforced concrete column. Through the analysis of three different calculation models and the overall index comparison, the results show that the connection property of the  column of concrete-filled square steel tubular short column is between the hinge and rigid connection, and it belongs to semi-rigid connection. In the structural simplification calculation, the overall control index should take the intermediate value of the calculation assumptions of hinge and rigid connections. According to the relevant requirements of Technical code for concrete filled steel tubular structures(GB 50936—2014), the bearing capacity of concrete-filled square  steel tubular  columns under single stress state and complex stress state was verified. The results show that the concrete-filled square steel tubular  columns meet the performance requirements under different stress states. Through the analysis of the whole and local joints, it is verified that the constructed joint is safe and reliable, and it can be used as reference for similar project design.

Keywords:traditional style building; structural model; joint design; joint construction
