抗震结构的动力优化设计研究

Dynamic Optimal Design of Aseismic Structures

从结构动力学基本方程出发 ,导出动力优化的抗震设计方法 ,通过动力优化降低了结构的动力反应 ;同时利用能量设计法建立了结构动力优化的目标函数 ,其与动力最优控制中性能指标具有形式上的统一 ;并基于地震随机性 ,提出了结构动力优化 。

Based on the basic equation in structural dynamic mechanics,a dynamic optimal design for reducing the dynamic response of structures is obtained.An objective function model is established with energy design method,which has the same form with the function target of dynamic optimal control.On account of the stochastic characteristics of earthquakes,a model designed for dynamic opportunity restraint program is applied.
