Abstract The research in this paper is based on a reinforcement project. The structure is covered by a skinned copper plate supported by the internal steel frame. The skin portion is mapped by 3D scanning technology and UAV (Unmanned Aerial Vehicle) photography. In this process, the skin portion is converted into point cloud data. On this basis, these data are converted into a surface for finite element simulation, which is combined with the internal steel frame to form an integral model. Based on the model, the seismic performance analysis of the structure was carried out by using the incremental dynamic analysis method. The results show that the design scheme of the internal steel frame satisfies the requirements of the seismic performance of the whole structure by the evaluation index of inter-layer displacement. The modeling method proposed in this paper can be used for the verification of existing structural reinforcement and transformation, based on which the bearing capacity and safety of the structure are evaluated.
