Optimally Distribution of Metallic Dampers Based on Genetic Algorithm and Sap2000 Application Programming Interface

在基于遗传算法的优化布置方法框架下提出了利用MATLAB遗传算法工具箱调用Sap2000的应用程序接口来执行优化算法的新技术。在该技术基础上,提出了一种新的目标函数,通过读取阻尼器的滞回耗能曲线数据使得所布置的阻尼器更高效地耗能。结合某办公楼结构算例,验证了该方法的有效性。

In this paper a new technique of optimally distribution of dampers is put forward.This technique is developed on the basis of global optimization toolbox of MATLAB calling Sap2000 application programming interface （API） to execute the optimization algorithm.Combined with this technique,a new fitness function is also presented to enable the dampers to dissipate energy more efficiently.At last,the technique and the fitness function are verified by an example.
