Based on the well-studied bearing equations of large steel structure bridge, this paper calculates the relationship between quality parameter matrix of the bridge and damping parameter, infers changing trends of stiffness bearing deformation matrix over time, and sets the effective threshold to alarm dangerous conditions in deformation. The paper summarizes the natural frequency of different forms of the bridge, and calculates the frame deformation situation caused by horizontal alternating force under high pressure.
