摘要

摘要: 密肋复合墙结构是集承重、围护、节能、抗震于一体的新型建筑结构。它由隐形框架、密肋复合墙板、楼板装配整浇而成,具有多道抗震防线并可分阶段释放地震能量。鉴于结构地震反应的强弱与墙体抗侧刚度的大小密切相关,在试验研究基础上,利用大型通用有限元软件ANSYS建立了密肋复合墙体的非线性有限元分析模型,对填充不同弹性模量砌块墙体在水平荷载和竖向荷载共同作用下的抗侧刚度进行了分析,并与试验结果对比表明:填充材料的弹性模量对墙体抗侧刚度影响较大,基本呈现线性相关关系。建立的复合墙体非线性有限元模型具有较好的实用价值,可为密肋复合墙结构设计提供参考。

Abstract: The multi-ribbed composite wall is a new building structure which possesses the characteristics of the load-bearing,enclosure,energy saving and anti-seism.It is monolithically cast of the invisible frame、prefabricated multi-ribbed composite wall and the floor,which has multi-line to act against earthquake and can release earthquake energy by stages.In view of the fact that the act against earthquake response is closely related to the wall lateral stiffness,it is established the nonlinear finite element model of the multi-ribbed composite wall with ANSYS based on the experiment study.Under interaction of the horizontal load and the vertical load,different FEA models are built with different materials,almost a linear correlation between filled block elastic modulus and the wall's lateral stiffness,comparing the analysis result with the experiment one shows,that the model has certain practical value,which can provide reference calculations for the structure design.
