The invention relates to an externally-attached cup mouth type socket-and-spigot type connection prefabricated assembly bridge pier. The externally-attached cup mouth type socket-and-spigot type connection prefabricated assembly bridge pier is connected with a lower structure. The externally-attached cup mouth type socket-and-spigot type connection prefabricated assembled pier comprises a prefabricated pier body and a cup mouth assembly. The cup opening assembly comprises cup opening stirrups and cup opening concrete; cup rim longitudinal ribs are arranged on the lower structure; the cup opening stirrups are bound in the circumferential direction of the prefabricated pier; the cup rim longitudinal bars are positioned through cup rim stirrups; the upper ends of the cup-opening longitudinal bars are arranged in the externally attached cup-opening type socket-and-spigot type connection prefabricated assembled bridge pier, and the lower ends of the cup-opening longitudinal bars are fixed in ...

The invention relates to a double-roll-shaft friction pendulum seismic mitigation and isolation support and application thereof. The double-roll-shaft friction pendulum seismic mitigation and isolation support comprises an upper seat plate, a lower seat plate, an FRP stiffening layer, roll shafts and a fixing support. One side of each of the upper seat plate and the lower seat plate is an arc surface and corresponds to the roll shaft; the roller shaft is fusiform, and the curvature radius of the generatrix of the roller shaft is the same as that of the arc surfaces of the upper and lower seat plates, so that the roller shaft is in linear contact with the upper and lower seat plates; and the distance between the two roll shafts is kept unchanged by the fixed bracket. Compared with the prior art, a rolling friction mechanism is adopted for shock absorption and isolation, compared with a sliding friction support, the structure period can be prolonged to the maximum extent, shearing force transmitted ...

The invention relates to a multi-stage buffering inhaul cable damping support which comprises an upper cover plate, an upper seat plate, a support body, a lower seat plate, a lower cover plate, anchor bolts, SMA inhaul cables, CFRP inhaul cables and inhaul cable hole channels. The SMA inhaul cable and the CFRP inhaul cable penetrate through reserved inhaul cable hole channels in the upper base plate and the lower base plate of the support, and the ends of the SMA inhaul cable and the ends of the CFRP inhaul cable are connected through connectors to form a closed ring shape. The free path of the SMA inhaul cable is smaller than that of the CFRP inhaul cable, when the earthquake vibration intensity is small, the two inhaul cables do not work, and the inertia force of the upper structure is transmitted only through the support body; when the earthquake vibration intensity reaches medium, the SMA inhaul cable begins to work, dissipates part of energy and inhibits rapid growth of bridge earthquake ...
