A sliding pendulum bearing is used to protect a construction against dynamic stresses from predominantly horizontal earthquake excitation with a first sliding plate, a second sliding plate and a slider movably arranged between both sliding plates, wherein each of the two sliding plates has a curved main sliding surface and the slider is in surface contact with a first main sliding surface of the first sliding plate and with a second main sliding surface of the second sliding plate, wherein the first main sliding surface is designed for a first load case and the second main sliding surface is designed for a second load case which differs from the first load case.

A first arch and second arch are produced in respective first and second structural portions. Each arch has a tie rod interconnecting the foot points of the arch, where a foot point of the arch is displaceably mounted. Each tie rod is tensioned so that horizontal forces caused by the weight of the arches at the foot points of the corresponding arch, are taken up by the tie rods. A first end point of the tie rod of the first arch is connected in a force-fitting manner to the first abutment, and a second end point of the tie rod of a last arch is connected in a force-fitting manner to the second abutment. The remaining adjoining end points of the tie rods are connected to one another in a force-fitting manner, and corresponding foot points of the arches are connected in a force-fitting manner to the abutments and pillar.

Structural support (1) including a first support portion (2) delimiting at least one containment compartment (4, 4); a second support portion (6) at least partly in front of the containment compartment (4, 4); and a sliding element (4), housed in the containment compartment (4, 4) and interposed between the first (2) and the second (6) support portion. The sliding element (8) substantially consists of a thermo-processable fluoro-polymer with a melt-mass flow rateaccording to the ISO 1133-1:2011 standardof less than 5.0 grams/10 minutes, for example under 3.0 grams/10 minutes.

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.

A bridge with a support structure supporting a deck section provided with at least one energy-converting device for converting kinetic energy into electrical energy. The energy-converting device is at least partly positioned in or on a bridge bearing and/or the energy-converting device at least partly used as a bridge bearing at the same time.

Disclosed are a damping bearing in convertible antiseismic mode and a damping bridge apparatus. The damping bearing includes a bearing body, a damping component, a hydraulic component, and a connecting piece. The bearing body includes a first bearing, a second bearing, and a third bearing. The damping component includes an arc damping member. The arc damping member is located between the first bearing and the second bearing. One end of the arc damping member is connected to the second bearing, the other end of the arc damping member is connected to the first bearing by using the connecting piece, and after the connecting piece is cut off, the arc damping member is capable of sliding relative to the first bearing. The hydraulic component is connected to the arc damping member and the second bearing respectively.
