[提要]  結(jié)合大連遠(yuǎn)洋大廈的彈塑性動(dòng)力時(shí)程分析，介紹一個(gè)便于實(shí)際工程應(yīng)用的高層建筑空間彈塑性時(shí)程分析程序HBFA。由于引入了考慮空間耦合作用的桿件彈塑性本構(gòu)模型，故可以用三維桿系-層模型對(duì)包括鋼結(jié)構(gòu)在內(nèi)的剪力墻可以任意布置的復(fù)雜高層建筑的彈塑性地震反應(yīng)進(jìn)行計(jì)算分析，獲得相應(yīng)的時(shí)程曲線及反應(yīng)包絡(luò)圖。

By introducing the analysis of Dalian Ocean Edifice, a practical spatial elasto-plastic time-history analysis program of high-rise building is pressented, which is named HBFA. As a new multi dimensional restoring force model for slender, thin-walled R.C.and steel beam-columns subjected to cyclic biaxial bending with axial load is proposed for the analysis of high-rise buildings affected by earthquake, we can use member-storey model to analyze the responses of complex structures with walls arbitrarily collocated and steel structures, and easily obtain the structural responses such as envelops of storey shear force, storey drift etc. and time histories of any appointed positions.
