摘要

摘要: 生态复合墙体作为生态复合墙结构的主要受力构件,它是由生态复合墙板与隐形外框组成的墙肢或墙段。鉴于开洞对墙体抗侧刚度影响较为显著,通过对1/2模型开洞生态复合墙体和标准不开洞生态复合墙体进行试验研究,对比分析二者的破坏模式及抗震性能。通过验证后的数值模型建立墙体扩展试验,分析其影响因素对开洞生态复合墙体抗侧刚度的影响程度并建立开洞生态复合墙体抗侧刚度计算公式,对比试验、数值与理论计算结果,验证计算公式正确性。理论计算结果与试验结果对比可得出:开洞生态复合墙体抗侧刚度计算公式具有一定的精度,能满足实际工程的要求。

Abstract: Eco-composite wall acting as the main bearing member of the Eco-composite wall structure is made up ofconcealed frame and eco-composite slab．Due to the significant impact of the hole on the lateral stiffness of the wall, through test of 1/2 model of open-hole eco-composite wall and that without open-hole, it was compared their failuremode and seismic performance．Through validated numerical modeling, the wall extension trial was established, andthe degree of impact factors on resist lateral stiffness of open-hole eco-composite wall was analyzed and the formula oflateral stiffness of open-hole eco-composite wall was set up, and the correctness of the formula was verified, throughthe test and the results of numerical and theoretical calculations．Comparing the results of theoretical calculations withtest ones shows that the formula of lateral stiffness of open-hole eco-composite wall has a certain accuracy, which canmeet the project requirements．
