【摘要】 结合大连远洋大厦的弹塑性动力时程分析,介绍一个便于实际工程应用的高层建筑空间弹塑性时程分析程序HBFA.由于引入了考虑空间耦合作用的杆件弹塑性本构模型,故可以用三维杆系-层模型对包括钢结构在内的剪力墙可以任意布置的复杂高层建筑的弹塑性地震反应进行计算分析,获得相应的时程曲线及反应包络图.更多还原

【Abstract】 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.更多还原
