ULTIMATE CAPACITY ANALYSIS OF ECO-COMPOSITE WALL

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。

Eco-composite wall acting as the main bearing member of an eco-composite wall structure is consisted of concealed frame and eco-composite slab. The ultimate capacity analysis of eco-composite wall is the main contents of the analysis of the structural ultimate bearing capacity and seismic performance evaluation. According to the mechanical behavior and failure process of the wall, shear resistant mechanism of eco-composite wall under limit state of bearing capacity was proposed. The calculating equations for ultimate strength were provided from shear resistant mechanism and equilibrium conditions, and at the same time it was analyzed the ultimate bearing capacity of the preliminary research walls. Theoretical researches and experimental analysis show that the model can better reflect the ultimate strength properties of the ecological composite wall, can be applied to check the ultimate strength under different load conditions of the ecological composite wall.
