[摘要]為研究預(yù)制夾芯保溫L形剪力墻在低周反復(fù)荷載作用下的受力性能、破壞特點和抗震性能,對4個夾芯保溫L形剪力墻試件(3個為全預(yù)制試件,1個為現(xiàn)澆對比試件)進(jìn)行擬靜力試驗,研究各個試件的破壞形態(tài)、承載能力、滯回曲線、骨架曲線、剛度退化及耗能能力。試驗結(jié)果表明:軸壓比對預(yù)制夾芯保溫L形剪力墻抗震性能的影響明顯;預(yù)制夾芯保溫L形剪力墻具有良好的抗震性能,可代替現(xiàn)澆夾芯保溫剪力墻用于實際工程中。[關(guān)鍵詞]預(yù)制夾芯保溫剪力墻; L形截面; 低周反復(fù)荷載; 抗震性能中圖分類號:TU375 文獻(xiàn)標(biāo)識碼:A 文章編號:1002-848X(2016)10-0020-04
Low frequency cyclic loading tests of L-shaped precast sandwich insulation shear wallSong Ge1, Wang Yong2(1 School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai 200093, China; 2 Department of Art and Design, University of Shanghai for Science and Technology, Shanghai 200093, China)Abstract: To study the mechanical behavior, failure feature and seismic behavior of L-shaped precast sandwich insulation shear wall, pseudo-static tests on four L-shaped precast sandwich insulation shear wall specimens (including three wholly precast specimens and one cast-in-situ specimen for comparison) were conducted to study the failure mode, bearing capacity, hysteretic curve, skeleton curve, stiffness degradation and energy dissipation capacity of specimens. The results show that: the influence of the axial compressive ratio on the seismic behavior of the L-shaped precast sandwich insulation shear wall is obvious; L-shaped precast sandwich insulation shear wall has good seismic behavior and it can be a good substitute for in-situ sandwich insulation shear wall used in practical engineering.Keywords: precast sandwich insulation shear wall; L-shaped section; low frequency cyclic loading; seismic behavior
