高层建筑二维风致响应实测中测点的优化布置方法

摘要

The determination of the optimal locations of sensors for two-dimensional full-scale measurements of 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 two-dimensional wind-induced responses of a tall building is used as an example to illustrate the application of the proposed method.%对高层建筑二维风致响应实测中测点的优化布置方法进行了研究.研究了在二维风致响应条件下测点优化布置的适应度函数,并且应用最优化计算方法来寻找的测点最优或接近优化布置.还通过一个高层建筑风致响应测试的实例,说明了具体的应用方法,实际计算表明用该方法布置测点所测得的结构风致响应结果有相当高的精度.
