MRD结构的动力反应分析
|
摘要
建立了MRD结构的动力分析模型,推导出结构运动微分方程。采用IOC算法控制策略,并采用Newmark法进行逐步计算,得到结构位移、速度和加速度时程。结果表明各种地震反应时程均收敛,并且各项地震反应均得到较好地控制。
The dynamic analysis model for MRD structure was set up.Kinetic differential function was derived out.IOC algorithm control strategy was used,and newmark method in the meantime was adopted in the calculation.Structure displacement,velocity,acceleration time history were obtained.The result expatiated that all the earthquake response time history were all convergent,and every different earthquake response was controlled very well.
