本文提出了一种从钢桁梁桥的点云数据半自动构建分析模型的方法。在端横支撑结构试验和再现分析的基础上，提出了桁架桥的实用分析模型。为了对大型既有桥梁进行有效的抗震加固，需要建立有效的分析模型。因此，表示目标的3D特征的点云被用于构建分析模型而不使用图纸。将该方法应用于某桁架桥端横撑点云，通过结构试验和再现性分析验证了该方法的准确性。
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.
