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。复合墙体的极限承载力分析是生态复合墙结构体系极限承载力分析和抗震性能评价的主要内容。鉴于墙体受力特性及破坏过程,给出承载力极限状态时生态复合墙体的抗剪抵抗机构;基于抗剪抵抗机构力的平衡条件,推导出复合墙体的极限承载力的计算公式,并对前期试验墙体进行极限承载力分析;理论和试验表明:该分析模型能够较好地反映生态复合墙体的极限承载力特性,可用于不同受力状态下生态复合墙体的极限承载力验算。
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 ultimate bearing capacity of composite wall is the main content of the ultimate bearing capacity analysis and seismic performance evaluation of the composite wall system. In view of the mechanical properties of the wall and the process of failure, the shear resistant mechanism of the ecological composite wall is given under the limit state of the bearing capacity. Based on the equilibrium conditions of the shear resistant mechanism force, the formula of the ultimate bearing capacity of the composite wall is deduced. And the ultimate bearing capacity of prestressed test wall is analyzed. The theoretical and experimental results show that this analytical model can better reflect the ultimate bearing capacity of ecological composite wall and can be used for the ultimate bearing capacity of ecological composite wall under different stress Check.
