摘要 在连续状态方程建立的IOC(瞬时优化控制)算法的基础上,直接根据高层建筑结构动力学方程导出了离散域的IOC算法,在性能泛函中加入加速度反馈项,并采用一El波作用下的10层剪切型建筑模型进行了模拟计算。计算结果表明,IOC控制算法对位移、速度、加速度和层间位移响应均有较好的控制;在主动作动器输入能量基本相等的情况下,改进IOC控制算法在结构高层部分的位移、速度和加速度响应及低层部分的层间位移响应控制效果优于传统IOC控制算法。 在连续状态方程建立的IOC(瞬时优化控制)算法的基础上,直接根据高层建筑结构动力学方程导出了离散域的IOC算法,在性能泛函中加入加速度反馈项,并采用一El波作用下的10层剪切型建筑模型进行了模拟计算。计算结果表明,IOC控制算法对位移、速度、加速度和层间位移响应均有较好的控制;在主动作动器输入能量基本相等的情况下,改进IOC控制算法在结构高层部分的位移、速度和加速度响应及低层部分的层间位移响应控制效果优于传统IOC控制算法。
