【摘要】 随着城镇化建设的飞速发展,多层住宅已经不能满足人们的需求,为解决实际问题提出中高层生态复合墙体结构体系。本文在保持原有生态复合墙原有诸多优点基础上,根据中高层生态复合墙体的受力特点和破坏模式,建立复合墙体软化拉-压杆模型进行研究,通过拟合参数有限元分析,进一步提出了统一的斜截面承载力公式,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,可应用于不同受力状态下生态复合墙体的极限承载力验算。更多还原

【Abstract】 With the rapid development of urbanization construction,multistory residence can’t satisfy people’s requirement. Under the circumstances,high-level ecological composite wall structure system is put forward to solve the problems. The article keeps lots of the original advantages of the ecological composite wall and according to mechanical characteristics and failure modes of the high-level ecological composite wall,establishes composite wall softening pull-push rod model and researches it. Through the finite element analysis of the fitting parameters,this paper further proposes an unified inclined section bearing capacity formula. The analysis model can reflect the ultimate bearing capacity of the composite wall well and can be applied to ultimate bearing capacity checking computations of the ecological composite wall under different stress states.更多还原
