and l, repeating the function executed in the step i by the information transfer module, reading and collecting the coordinate information, the stress information and the deformation information of each unit node of the finite element model in the new rst file, reconstructing and data mapping in the three-dimensional model of the BIM bridge operation and maintenance management module according to the coordinate information of the nodes, and visually displaying the stress and deformation conditions of each node of the bridge by color gamut change so as to synchronously update the operation and maintenance information of the bridge and the finite element calculation result.
