摘要
通过对多层砌体结构的生态节能复合墙体破坏模式研究,结合墙体的受力行为分析,提高生态节能复合墙体结构强度和应力响应水平,提出基于弹性滞回力学分析的多层砌体结构生态节能复合墙体破坏模式定量分析模型。构建生态节能复合墙体的屈服应力响应特征量,采用承载力负荷加载方法进行多层砌体结构的生态节能复合墙体的应力负荷及屈服强度分析,采用侧向荷载检测方法对生态节能复合墙的断裂抗拉力进行统计特征分析,根据断裂预估方法实现墙体破坏模式研究。采用有限元分析软件进行墙体破坏模式模拟和力学分析,从而为指导墙体施工提供数据基础。
Through the study on failure mode of ecological energy saving composite wall of multistory masonry structure,force analysis of wall combination,this study improves eco composite wall structure strength and stress response level,put forward analysis model to the elastic hysteresis of multistory masonry structure eco composite wall failure mode based on quantitative,yield stress response characteristic quantity the construction of ecological composite wall,the stress analysis of load bearing capacity and yield strength loading method of ecological energy saving composite wall masonry building,the lateral load detection method of fracture on the ecological energy saving composite wall and the tensile statistical characteristic analysis,according to the fault prediction method of failure mode analysis. Research on wall damage model simulation and mechanics using finite element analysis software were taken. The test results show that this method can accurately simulate the students the behavior characteristics of the state energy saving composite wall damage behavior have improved the ability to evaluate the stress of the wall,thus providing the data basis for guiding the wall construction.
