高层建筑动力反应实测中测点的优化布置方法的研究

Optimal sensor locations for measurements of dynamic responses of tall buildings

本文对高层建筑动力反应实测中测点的优化布置方法进行了研究,研究了几种表示测点布置是否最优的适应度函数,并且应用最优化计算方法来寻找测点最优或接近优化的布置。本文还通过一个高层建筑动态响应测试的实例,说明了具体的应用方法。实际计算表明,用本文方法布置测点所测得的结构动态响应结果有相当高的精度。

The determination of the optimal locations of sensors for dynamic measurements and health monitoring of super tall building is useful for the purposes of achieving the reduction of test cost and improving the accuracy of measurements. In this paper, an efficient method is established for the determination of optimal sensor locations. The measurement of the dynamic responses of a super tall building is used as an example to illustrate the application of the proposed method.
