A seismic reinforcement device for a bridge includes a first member having a projecting portion and a second member having a depressed portion. The device has a horizontal force sharing function in which the projecting and the depressed portions are freely fitted to and engaged with one another to constitute a shear key and resist a horizontal force by causing the first member to be coupled to and supported by any one of the substructure and the superstructure and causing the second member to be coupled to and supported by the other of the substructure and the superstructure. In addition, the device has a level difference preventive function that suppresses dropping of the superstructure and reduces a level difference of the substructure and the superstructure by interposing a spacer having a predetermined thickness between the first and second members or between the substructure or the superstructure and the device.

The present invention relates to a structural sliding bearing 210 for connecting a first structure part to a second structure part. The structural sliding bearing 210 has a bearing base 212 connectable to the first structure part, a sliding plate 216 connectable to the second structure part, and an intermediate bearing part 214 disposed between the bearing base 212 and the sliding plate 216, wherein a primary sliding surface 226 of the structural sliding bearing 210 is disposed between the intermediate bearing part 214 and the sliding plate 216. The primary sliding surface 226 has at least two partial sliding surfaces 228A and 228B, each arranged in sliding planes 230A and 230B angled relative to one another, the sliding planes 230A and 230B meeting at a common line of intersection S that forms an axis of movement A of the structural sliding bearing 210 along which the sliding plate 216 can move. The two sliding planes 230A and 230B include a first angle , the first angle being selected such that no gap occurs in the area of the primary sliding surface 226 when the structural sliding bearing 210 is in use. Furthermore, the invention relates to a structural bearing system 700 in which the advantageous principle of the structural sliding bearing 210 is applied.

The present disclosure provides a rear-anchored V-shaped pier of a steel structure of a three-legged star-shaped pedestrian landscape bridge and a construction method. The rear-anchored V-shaped pier of a steel structure of a three-legged star-shaped pedestrian landscape bridge is applied to a main bridge arch that includes three arch legs connected into a star shape having three legs, and includes a deck-type arch-footed V-shaped pier, where the deck-type arch-footed V-shaped pier is disposed at a rear end of each arch leg. The deck-type arch-footed V-shaped pier has a top connected to the arch leg and a bottom hinged with a pile foundation of a bearing platform pre-poured on a construction ground.
