In this paper, a method to semi-automatically construct an analysis model from point clouds of steel truss bridges is proposed. The authors proposed practical analysis models of truss bridges based on structural experiment and reproduction analysis of end sway bracing. For efficient seismic reinforcements enormous existing bridges, it is necessary to construct analysis models efficiently. Therefore, point clouds that represented 3D features of targets are used to construct analysis models without using drawings. The proposed method is applied to point clouds of end sway bracing in a truss bridge and verified its accuracy based on structural experiments and reproduction analysis.
