Example Embodiment
[0025] Such as Figure 1 to Figure 7 As shown, a specific embodiment of an energy-dissipating steel bridge seismic block structure and arrangement method of a low yield point along the bridge of the present invention includes a steel corbel 9, a block body 10, and a steel frame 11. The bridge type selected in this embodiment is an I-shaped steel plate composite girder bridge, and the bridge seismic block structure and arrangement method are also applicable to other bridge types such as prestressed concrete bridges and steel bridges.
[0026] Such as Figure 1 to Figure 4 As shown, the main girder 1 of the bridge and the other main girder 2 of the bridge are disconnected at the top of the pier 4 to form an expansion joint 3. Along the bridge direction at the expansion joint 3, on the top of the pier 4, a bridge support cushion stone 5 and another bridge support cushion stone 6 are set, and the movable bridge support 7 is set on the bridge support cushion stone 5, and the bridge is...
