摘　　要：引入了考虑空间耦合作用的钢杆件弹塑性本构模型 ,对水平地震作用采用了不同振动模型 ,故可用空间杆系 -层模型对高层钢结构进行水平及竖向地震作用下的弹塑性动力时程分析 .在上述理论基础上编制了便于工程设计人员使用的程序HBTA ,利用该程序对算例进行了分析 ,并对一些问题进行了探讨 .A multi_dimensional elasto_plastic restoring force model is proposed for steel beam_columns,and different vibration models are proposed for horizontal and vertical earthquakes.It is suggested that the member_storey model be used to analyze the horizontal and vertical responses of high_rise steel frames.Based on the theory,a practical spatial elasto_plastic time_history analysis program is developed,which is named HBTA.Some conclusions are made based on calculation.
