本文就多层动力厂房的抗震提出了以优化动力设备基础的各参量来达到减小结构及动力设备自身在地震力作用下响应的理论。运用传递矩阵法推导出响应的计算公式,以外罚函数法对动力设备基础的弹簧刚度、阻尼系数、热层质量进行优化分析。并做了相应的模型实验以验证其理论及计算方法。
In this paper, the theory of the seismic response of the multi-story power plant is proposed to optimize the parameters of the power equipment foundation to reduce the response of the structure and the power equipment itself under the action of seismic forces. The transfer matrix method was used to derive the formula for the response. The external penalty function method was used to optimize the spring stiffness, damping coefficient, and thermal layer quality of the power equipment foundation. A corresponding model experiment was performed to verify its theory and calculation method.
