摘要: 鋼框架-鋼板混凝土組合墻結(jié)構(gòu)是一種適用于高層鋼結(jié)構(gòu)住宅的新型結(jié)構(gòu)體系,目前國內(nèi)規(guī)范還未對該體系進行相關(guān)規(guī)定. 為研究該結(jié)構(gòu)體系的抗震性能,以某高層住宅項目為例,建立了鋼框架-鋼板混凝土組合墻結(jié)構(gòu)數(shù)值模型,采用靜力彈塑性方法對該結(jié)構(gòu)大震下的抗震性能進行分析. 結(jié)果表明:該結(jié)構(gòu)在整體與構(gòu)件層次均滿足抗震性能目標的要求?框架柱剪力分擔率隨結(jié)構(gòu)塑性的發(fā)展而提高,結(jié)構(gòu)塑性發(fā)展順序符合預期,具有多道抗震防線?組合墻抗剪能力有較大富余,框架柱少量進入塑性狀態(tài).

Abstract: Steel frame-steel and concrete composite wall structure is a new type of structural system suitable for high-risesteel structure residences. At present, no relevant provisions for this system have been specified in domestic codes. In orderto study the seismic performance of this structural system, a numerical model of steel frame-steel and concrete compositewall structure was established as an example for a high-rise residential project, and the seismic performance of this structureunder rarely occurred earthquake was analyzed using the static elastoplastic method. The results show that the structuremeets the requirements of seismic performance objectives at both the structure and component levels;the shear forcesshared by frame columns increases with the development of structural plasticity, and the sequence of structural plasticitydevelopment is as expected, with multiple seismic defense lines;the composite wall has a large surplus of shear resistance,and the frame columns enter the plastic state in small amounts.
Keywords:steel frame-steel and concrete composite wall strueture;performance-based seismic design;Pushover analysis?multiple seismic defense lines
