PRECISION MEASUREMENT OF LOCAL DEFORMATION IN WELDED MEMBERS USING A VISUAL MONITORING SYSTEM

摘要：

In the loading tests for welded steel members, local deformation and strain in welded joints are difficult to accurately measure due to the effect of welding residual stress and weld metals. Therefore, a precision measurement system is required to observe the local deformation of welded members. In this paper, to accurately measure the welded steel members, a visual monitoring system(VMS) used a three-dimensional digital photogrammetry is developed by the authors. And distributions of strain adjacent to welded joint are investigated by using the VMS.
