摘　　要：某厂筛分楼内安装有动力设备,该动力设备形成振动源产生动力荷载,使筛分楼的振动问题十分复杂。本文在分析筛分楼结构的基础上,应用SAP2000有限元软件对平台结构进行建模及动力学仿真计算,计算出结构的振型与频率,从计算结果预测工业厂房的振动情况,为改善结构设计提供参考意见。There are some power equipments installed in the platform of a certain factory.The power equipments form a vibration source to generate dynamic loads,which makes the vibration problem of the building very complicated.Based on the structure analysis,the reinforced concrete structure was researched and the finite element model of the built was built in SAP2000 software.The vibration mode and frequency of the building were calculated.The simulation results provide a favorable reference for structural design.
