摘要

An accurate method for remotely measuring structure microtremors is proposed by using an improved Laser Doppler Velocimeter (LDV). The remote microtremor measurements of a rigid-frame structure model and an existing RC rigid-frame structure are presented in order to verify the efficiency of the proposed method. Dynamic structural characteristics, such as the natural frequency and the fundamental mode shape, of the model and the RC structure are accurately estimated.
