| 摘 要： | 相邻结构问的滞变支撑连接能有效缓解结构的地震响应.国际上广泛采用基于求解Lyapunov微分方程的随机振动法解决该类问题.Lyapunov法的地震输入局限于散粒噪声,限制了该方法的工程运用.本文假设结构始终保持线弹性,用Bouc-Wen模型模拟非线性滞变恢复力,通过扩阶、降阶矩阵的使用,结合随机等效线性化法,导出滞变支...

| Abstract: | Hysteretic dampers have been widely used in the reactor coolant piping system as the energy absorbing components.In the paper,the random seismic response is evaluated through the pseudo-excitation principle incorporated with stochastic equivalent linearization method without by solving the Lyapunov differential equation for which the seismic excitation at support is limited to be shot noise process.It is supposed that the structures keep elastic and the hysteretic dampers are represented by the versatile Bo... |
