不同内填材料的生态复合墙结构地震反应分析

Seismic response analysis on the eco-composite analysis wall structure in-filled with different materials

生态复合墙体作为一种新型的生态环保住宅结构体系,其内填材料要满足因地制宜、就地取材的原则,本文在课题组已研发和应用的五种生态复合墙体材料的基础上,采用经过验证的刚架-复合弹性板力学模型,对结构进行弹性阶段的动力反应对比分析,并模拟原型结构在弹性阶段的动力特性.利用该模型对某工程实例分析研究,计算分析结果表明:在多种地震波作用下,内填石膏砌块墙体频率最大,其余四种材料频率较为接近,内填草砖时频率最小;当内填草砖时,侧移及层间位移最大,内填陶粒块和发泡块时,侧移及层间位移较为接近,而内填石膏时最小;五种不同内填材料的楼层加速度曲线趋势大体趋于一致.

Composite wall is a new type of ecological environmental protection residential structure system, and its fill material can meet the principle of adjust measures to local conditions. This paper is based on five kinds of ecological composite wall material which the group had researched and developed, using proven frame - composite elastic plate mechanics model to contrast analysis of the structure of elastic stage dynamic response and simulate the dynamic performance of the prototype structure in elastic stage. Analysis by using the model of a certain engineering example, calculation and results show that under many kinds of seismic wave, the filling of gypsum block wall peak frequency, frequency of the rest of the four kinds of material is close, frequency is the minimum when filled with the grass brick. When filled with the grass in brick, the lateral displacement and displacement between the layers is the largest. When the wall is filled with ceramsite block and foam block, the lateral displacement and displacement between the layers is relatively close, and it is minimum when filled with gypsum. The wall is filled with material within the five different material floor acceleration curve trend generally tend to be more consistent.
