【摘要】 按比例设计制作钢框架结构缩尺模型,用计算机控制振动台按地震波在4种不同台面加速度下振动,采集模型结构多个控制截面处的动态应变值,并建立相应的各工况有限元模型,分析相应位置的工作应变。通过对比发现,试验与理论分析结果误差很小,基本吻合。更多还原

【Abstract】 The steel frame structure scale model is designed and manufactured proportionally,and the vibration table is used to vibrate according to the seismic wave at four different mesa accelerations.The dynamic strain values at multiple control sections of the model structure are collected,and the corresponding finite element models of each working condition are established to analyze the work strain at the corresponding location.Through comparison,it is found that the error between the experimental results and theoretical analysis results is small,and they are basically consistent.更多还原
