The utility model provides a structural system for improving three-way static and dynamic response of a large-span suspension bridge structure. The bridge is characterized in that the bridge comprisesmain beams, bridge towers, main cables, suspenders, anchors, metal energy consumption type central fasteners, displacement type control dampers, elastic damping wind-resistant supports and vertical elastic tension-compression supports, K pairs of metal energy consumption type central fasteners are arranged between mid-span cable beams in the longitudinal direction of the bridge, K is a natural number, and the displacement type control dampers are longitudinally arranged between the tower beams; the elastic damping wind-resistant support is installed between the transverse bridge direction main beam and the inner side of the bridge tower, and the main beam and the bridge tower are transversely connected. Elastic tension and compression supports are arranged at the top of a lower beam of the bridge tower and the bottom of the main beam to vertically connect the main beam with the bridge tower. Additional rigidity and additional damping are reasonably set for the large-span suspension bridge, three-way stress and deformation of the structure under static and dynamic loads are effectively controlled, the stress performance of the structure is improved, the scale of a telescopic deviceis reduced, and the economy of the suspension bridge is improved.
