基于统一强度理论生态复合墙体受剪极限承载力分析
|
摘要
基于试验研究及理论分析,结合生态复合墙体受力特性、破坏过程及破坏模式,提出生态复合墙体复合材料等效弹性板模型;建立生态复合墙体整体斜压杆计算模型。采用适用于各种材料复杂应力状态下的双剪统一强度理论,推导出生态复合墙体的受剪极限承载力计算公式,应用此公式对前期试验墙体进行分析。将理论结果与试验数据进行对比分析,结果表明:该模型能够较好的反应生态复合墙体的极限承载力特性,可用于不同尺寸、配筋和内填材料生态复合墙体的极限承载力验算。
Based on theoretical analysis and experimental research,combined with the mechanical characteristics,failure process and failure mode of eco-composite wall,a composite materials equivalent elastic plate model of eco-composite wall was proposed;a calculation model of whole compressive diagonal strut for eco-composite wall was set up.Twin shear unified strength theory was applied to deduce the ultimate shear bearing capacity formula of eco-composite wall,with which an analysis of the preliminary research walls was carried put.The theoretical results were compared with experimental data,the result show that the model can better reflect the ultimate bearing capacity properties of the ecological composite wall,which can be applied to check the ultimate shear bearing capacity under different sizes,reinforced and filled materials of the ecological composite wall.
