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。
As the main force component of the ecological composite wall structure, the ecological composite wall is a wall limb or wall segment composed of an ecological composite wall plate and an invisible frame. In view of the obvious influence of the open hole on the lateral stiffness of the wall, the failure mode and the anti-seismic performance of the two models are compared through the experimental study on the 1/2 composite open-hole ecological wall and the standard non-open-hole ecological composite wall. Through the verified numerical model, the expansion test of the wall is established. The influence of the influencing factors on the lateral stiffness of the ecological composite wall is analyzed and the calculation formula of the lateral stiffness of the ecological composite wall is established. The comparison test, numerical and theoretical calculation As a result, verify the formula correctness. Comparing the theoretical calculation results with the experimental results, it can be concluded that the calculation formula of lateral stiffness of open-hole ecological composite wall has certain accuracy and can meet the requirements of practical engineering.
