［摘要］為研究XPS夾心保溫復(fù)合墻在裝配式輕鋼框架內(nèi)的嵌入深度對(duì)結(jié)構(gòu)抗震性能的影響，設(shè)計(jì)了3個(gè)足尺試件，包括兩個(gè)XPS夾心保溫復(fù)合墻嵌入深度分別為150，60mm的試件和1個(gè)空框架試件。通過低周反復(fù)荷載試驗(yàn)，分析了裝配式輕鋼框架-XPS夾心保溫復(fù)合墻結(jié)構(gòu)的損傷演化過程、滯回曲線、骨架曲線、承載力與變形、承載力退化、剛度退化、耗能能力和應(yīng)變特征。結(jié)果表明：裝配式輕鋼框架-XPS夾心保溫復(fù)合墻結(jié)構(gòu)有效破壞位移大于位移角為1%對(duì)應(yīng)的位移，結(jié)構(gòu)變形滿足實(shí)際工程抗震設(shè)計(jì)的彈塑性位移角要求；復(fù)合墻嵌入輕鋼框架內(nèi)的深度對(duì)裝配式輕鋼框架-XPS夾心保溫復(fù)合墻結(jié)構(gòu)性能有顯著影響，不同嵌入深度下結(jié)構(gòu)承載能力及變形能力顯著不同；隨著復(fù)合墻板嵌入深度的增加，試件的承載力、變形能力、耗能能力等抗震性能有顯著提高。

Abstract:In order to investigate the influence of installation depth of the XPS sandwich insulation composite wall inside the assembly light steel frame on seismic performance of the structures, three full size specimens were designed. Two specimens with XPS sandwich insulation composite walls which installation depth in the frames were respectively 150mm and 60mm, and the last specimen were bare frame without wall. The low cycle repeated load tests were conducted. The damage evolution process, hysteresis curve, skeleton curve, bearing capacity and deformation, bearing capacity degradation, stiffness degradation, energy dissipation capacity and strain characteristics of the assembly light steel frame-XPS sandwich insulation composite wall structure were analyzed. The results indicate that the effective failure displacement of the assembly light steel frame-XPS sandwich insulation composite wall structure is greater than the displacement corresponding to the displacement angle of 1%, and the structural deformation meets the elastoplastic displacement angle requirements of the actual engineering seismic design. The effect of installation depth of composite wall in light steel  frame was significantly to the structural performance of assembly light steel frame-XPS sandwich insulation composite wall, which bearing capacity and deformation capacity are significantly different under different installation depth of composite wall. With the increasing of the installation depth of composite wall, seismic behavior such as bearing capacity, deformation capacity, energy dissipation capacity of each specimens et al. have significantly improvement.
