通过对轻钢结构的地震响应特征进行研究,采用有限元方法对轻钢结构模型进行非线性地震响应分析,研究顶层位移和其他各层位移的变化,比较60,100,120,160mm几种不同厚度楼板的地震波响应,得到计算模型的应变、应力关系。研究结果表明:不同厚度楼板对相同的地震波有不同的地震响应,当楼板厚度为120mm和160mm时,对地震波产生的响应最为强烈;多层轻钢结构具有很好的剪切变形;在多层结构设计时,应该根据具体要求定性分析和定量计算楼板厚度对抗震性能的影响。
Through the study of the seismic response characteristics of the light steel structure, the nonlinear seismic response analysis of the light steel structure model is carried out by finite element method to study the displacement of top layer and other layers. The seismic response of several floors with different thickness of 60, 100, 120 and 160 mm , Get the strain and stress of the model. The results show that different thickness of slabs have different seismic response to the same seismic wave. When the slab thickness is 120mm and 160mm, the response to seismic waves is the most intense. The multi-layer light steel structure has good shear deformation. Structural design, should be based on the specific requirements of qualitative analysis and quantitative calculation of the impact of the thickness of the floor seismic performance.
