中文摘要	采用考虑组合梁多材料截面引起的正向、负向刚度、强度和承载力不同的截面本构模型,建立了组合梁结构的弹塑性分析模型,对一个15层的钢混凝土组合梁-方钢管混凝土柱框架结构开展了多遇地震、罕遇地震下的pushover分析,为组合框架结构体系的抗震性能分析以及pushover方法在该体系中的应用提供了参考。在此基础上,与钢梁-方钢管混凝土柱框架结构、钢梁-钢筋混凝土柱框架结构进行对比研究,比较了几种结构的动力特性,表明组合梁-方钢管混凝土柱框架结构体系相对于其它两种框架结构体系具有更好的抗震性能。; Based on the sectional constitutive model under consideration of different positive and negative stiffness and strength due to the composite section,a finite element model of the composite beam for the dynamic elastic-plastic analysis is developed in this paper.A pushover analysis is performed for a 15-story composite beam and concrete-filled rectangular tube frame structure,which provides a reference for the seismic analysis of composite frame structures and the application of the pushover method to this system.And then the dynamic characteristics of this system are compared with those of frame structures which are composed of concrete-filled rectangular tubular columns,RC columns and steel beams.It can be concluded that the composite beam and concrete-filled rectangular tube frame structure is more advantageous in the aseismic performance.
