Research on optimal sensor placement for dynamic responses of high-rise building
摘要
Abstract
Wind load is one of the control loads of high-rise building. To reduce test cost and improve the accura-cy of measurements, it is necessary to find the optimal sensor placement for dynamic responses of high-rise building. In this paper, an automatic matlab program is created to solve the problem of linear interpolation of mode shape under the condition of random measurement points. Four traditional fitness functions of evaluating the similarity of mode shape are converted to the adaptive functions of improved partheno-genetic algorithm, which makes an automated process possible in the field of optimal sensor placement. The measuement of a high-rise building is used as an example to illustrate the application of the proposed method. It turns out that the method is efficient and suitable to be applied to high-rise structure and the vibration testing field of civil engineering struc-ture.关键词
