Evaluation of the Dynamic Characteristics of an Extradosed Bridge Using Microwave Interferometer

Abstract:

Article Preview

The microwave interferometer used in the present study is capable of multiple-point displacement measurements. In this paper, a general review of the principle and capacity of such an instrument is given. The vertical displacements of the Ai-Lan bridge corresponding to ambient vibration due to traffic loads are remotely monitored . Several modal shapes of the whole bridge are precisely identified by linking the mode shapes of seven sequential measurements.
