Abstract

Traditional contact sensors usually break with the failure of structures or model. To solve this issue, a stereovision-based 3D displacement measurement method is proposed to detect the whole process of structural deformations in this paper. A three-floor frame model subjected to earthquake excitation is tested with the proposed method in lab. Experiment results show good agreement with LVDT data during small deformation stage, this verifies that the presented approach is reliable. During large deformation stage, LVDT sensors are destroyed, the dynamic response curves of three-floor frame models are only acquired by the propose method. Experimental results prove that the proposed approach is feasible and useful for monitoring whole-process deformations of structures even at collapse stage.
