In recent years, the construction of new urban expressway routes required the application of unprecedented complex structures, such as significantly eccentric bridge piers, due to various constraints. When conducting load tests on such structures, it is anticipated that complex local buckling with twisting deformations, unlike anything seen before, may occur due to out-of-plane (bridge axis) loading. Therefore, traditional deformation measurement methods may not facilitate the prediction of deformation locations or the acquisition of diagonal deformations. In this paper, we report on the potential utility of measurement using a high-precision point cloud data acquisition scanner for out-of-plane loading experiments on highly eccentric concrete-filled steel bridge piers, with the aim of accurately capturing the complex local buckling shapes involving twisting deformations. This research investigation the possibilities for future applications.
