摘　　要：为了研究再生保温混凝土剪力墙的抗震性能,进行了3种不同剪跨比再生保温混凝土剪力墙的低周往复荷载试验。根据试验结果,分析了各试件在承载力、延性性能、滞回曲线、骨架曲线、刚度及其退化过程的特征。试验与分析结果表明:剪跨比对再生保温混凝土中高和低矮剪力墙延性影响不大,以及对高和中高剪力墙屈服前刚度衰减影响不明显;再生保温混凝土高墙及中高墙有明显的塑性变形阶段,耗能能力好,低矮墙易发生脆性破坏。In order to study the seismic behavior of recycled aggregate thermal insulation concrete shear walls, to take the low cyclic loading tests on 3 kinds of different shear span ratio of shear wall. Basing on the test results, to analysis of the specimen on the characteristics of bearing capacity, ductility, hysteretic curves, skeleton curves, the stiffness and its degradation process. The results of test and analysis show that： the shear span ratio on ductility of mid-rise and low-rise shear walls is has a small effect to the high-rise and mid-rise shear wall in the front of yield stiffness attenuation effect is not obvious ; Recycled aggregate thermal insulation concrete of high-rise and mid - rise shear walls in the stage of plastic deformation and energy dissipation capacity is obvious, the low - rise shear wall is prone to brittle failure.
