Analysis of Seismic Structure Stress Yield Based on Fiber Reinforced Concrete Damping Layer

研究了纤维增强混凝土减震层的墙体结构力学分析,采用有限元建模方式对混凝土材料的剪力墙和恢复力模型进行研究,构建纤维素混凝土减震层的框架核心结构。采用对高层建筑的层间位移角、层间速度和层间的墙体恢复力进行测试方法,得到地震冲击波作用下墙体结构的地震反应,最后得到减震层墙体的应力屈服响应分布图,有效指导减震层结构的优化设计。试验结果表明,设计模型能定量分析减震层的墙体力学结构,在高层建筑减震层墙体优化设计中具有很好的应用价值。

The analysis of fiber reinforced concrete wall structure mechanical damping layer is researched, and the finite el-ement model of shear wall is used to construct the concrete material and the restoring force model, the core structure of cel-lulose concrete damping layer is obtained. The inter story displacement angle, interlayer the speed and the interlayer wall resilience test method is used and the seismic response of the wall structure obtained seismic shock wave is obtained. The shock layer wall stress yield response distribution is reached. It is used to guide the damping layer structure design. Test re-sults show that the design of model can analyze the wall mechanical structure damping layer quantitatively. It has a very good application value in high-rise building design.
