【摘要】：為綜合評(píng)價(jià)現(xiàn)澆剪力墻預(yù)制框架半裝配式框架-剪力墻結(jié)構(gòu)的抗震性能,設(shè)計(jì)制作了2榀1∶2的2層2跨混凝土框架-剪力墻結(jié)構(gòu)模型試件,并對(duì)其進(jìn)行了低周反復(fù)荷載試驗(yàn).對(duì)比研究了這2榀試件的破壞機(jī)制、破壞過(guò)程、滯回性能、位移延性和耗能能力等抗震特性.試驗(yàn)結(jié)果表明,半裝配試件與現(xiàn)澆試件具有相近的開(kāi)裂位移、裂縫開(kāi)展形態(tài)、破壞模式、耗能能力和側(cè)向承載能力,但半裝配試件的延性略低,在不同承載狀態(tài)下的水平荷載也略低.現(xiàn)澆剪力墻預(yù)制框架半裝配式框架-剪力墻結(jié)構(gòu)的整體性較好,在地震中具有可靠的抗倒塌能力.
[Abstract]:In order to comprehensively evaluate the seismic performance of the semi assembled frame shear wall structure of cast in situ shear wall, 2 specimens of 1: 2 and 2 span concrete frame shear wall structure are designed and manufactured, and their low cyclic loading tests are carried out. The failure mechanism, failure process, hysteretic behavior, displacement ductility and ductility of the 2 specimens are compared and studied. The test results show that the semi assembled specimens have similar cracking displacements, fracture patterns, failure modes, energy dissipation capacity and lateral bearing capacity, but the ductility of semi assembled specimens is slightly lower and the horizontal load is slightly lower in different loading conditions. The semi assembled frame of cast-in-place shear wall prefabricated frame is a semi assembled frame. The shear wall structure has good integrity and reliable collapse resistance in earthquakes.
