摘要
以一小式木结构房屋台基为研究对象建立足尺模型,利用通用有限元分析软件ABAQUS对有无台基的模型分别进行了时程分析。通过提取屋盖结构的加速度、位移响应时程及结构最大Mises应力、最大侧移、柱根滑移量等参数,对两种模型进行了定量的对比。得出台基可有效缓解上部结构地震响应、控制柱倾斜量、提高柱根滑移隔震效率等结论。
A full-scale mechanical model is set up to simulate a small ancient wooden houses with platform.Time history analysis is applied to analysis the platform-model and non-platform-model in ABAQUS,a large finite element analysis software.The acceleration response and displacement response of roof,maximum von Mises stress and displacement of the model,and the slippage of the column roots are obtained.By comparing and analyzing the characteristics,it shows that the platform could effectively reduce the Seismic response of structure,limit column tilting,improve the slippage and shock isolation of column roots etc.
