| 摘 要： | 提出了地震作用下摩擦耗能支撑参数优化的一种新的数学模型。它的特点是在给定的几条地震波作用下，在满足框架的规范层间位移角限值要求下，框架各层安装的耗能支撑刚度之和最小，从而实现安装较少的耗能装置而能达到相同的抗震要求。本文利用遗传算法求解该优化问题，并编制了基于遗传算法的几条地震波分别作用下的摩擦耗能框架结构支撑参数弹塑性动力优化分析程序GAOFF。最后给出了一6层框架在三条地震波分别输入下的优化算例，分析结果表明本文方法是有效的。

| Abstract: | A new mathematic model of parameters optimization for braces with friction energy dissipation subjected to earthquake is established. The model is characterized with the minimized sum of brace stiffness complied with the codes of story-drift angle limitation in several given earthquake recorders. Therefore, the similar structure anti-seismic requirements can be satisfied with less friction energy dissipation devices. By using Visual C++ Language, a computer program GAOFF is developed to optimize the parameters of braces with friction energy dissipation subjected to several earthquake waves based on genetic algorithm. An example of six-storey-high frame is also illustrated to verify the new model. |
