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。复合墙体构造上的特殊性及多种材料的使用,使其弹性常数不易确定,进而影响墙体抗侧刚度的计算。基于前期试验研究,针对墙体独特构造,结合复合材料力学理论,建立适用于生态复合墙体的弹性阶段模型——双向纤维单层复合材料模型,推导出墙体弹性模量及剪切模量实用计算公式,为生态复合墙体的实用抗侧刚度计算公式提供必要的参数;利用弹性力学对各向异性等效弹性板的抗侧刚度进行推导,理论计算与试验结果的对比分析表明:在生态复合墙体抗侧刚度计算中,复合材料力学简化模型具有实用性和有效性。
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. The particularity of the composite wall structure and the use of a variety of materials, so that the elastic constant is not easy to determine, thereby affecting the wall stiffness calculation. Based on the previous experimental research, aiming at the unique structure of the wall and the mechanics theory of composite materials, the elastic phase model of composite wall is established, which is the bi-directional fiber single-layer composite material model, and the elastic modulus and shear modulus Practical calculation formula is provided to provide necessary parameters for practical stiffness calculation formula of ecological composite wall. Based on elasticity mechanics, the lateral stiffness of anisotropic equivalent elastic plate is deduced. Comparing the theoretical calculation and test results, In the calculation of lateral stiffness of composite wall, the mechanics simplified model of composite material is practical and effective.
