Abstract :
A simple force-based mesh division approach for the bridge is proposed in this paper. This method finds point position using force equilibrium, distance function and changes the topology by the Delaunay triangulation. The feasibility and accuracy of the proposed approach are confirmed using the simulation experiment of the bridge injury detection and the correct rate increases by 9.4%.
