The present invention discloses a bidirectional collapse-proof damper with a macroscopic NPR structure and a bridge structure having the same, comprising a sleeve and a sliding rod; by adding a structure of a reducing part and a limiting body, a sliding gap exists between both ends of the limiting body and both inner ends of the reducing part; the rod body is connected with the inner side wall of the sleeve through an elastic element; the limiting body and the rod body can realize bidirectional slip in the sleeve, which have multi-level seismic performance.

An article of manufacture for an earthquake safety protection device (ESPD) according to the present invention is disclosed. The ESPD consists of an earthquake support pole and mating support members to create survivable space around the support pole should a room be damaged in an earthquake. The ESPD may also comprise a reinforced frame within an interior door of a building. The reinforced frame resists damage from an earthquake that may prevent the interior door from opening. Opening or removal of the inner door protected by the reinforced frame creates a means of safely exiting a room in spite of damage to the interior door and its corresponding door frame. The ESPD may also include a mechanism to prevent a mobile hospital bed from moving about a room during an earthquake.

An anti-seismic performance reinforcement structure of a masonry structure and a construction method of the same are proposed, where a deformed bar is constructed to be tied to the entire circumference of the masonry structure at every predetermined height thereof such that the masonry structure is connected to a wall, thereby simplifying a construction process, and inducing the masonry structure and the wall to be moved integrally to each other during an earthquake so as to prevent the masonry wall from collapsing. The method of performing anti-seismic performance reinforcement and crack repair of the masonry structure includes: removing a predetermined depth of a horizontal joint; mounting the cross joint by forcibly press-fitting the cross joint having the press-in holder and the horizontal holder to a perforated position; fixing a deformed bar fixture to the wall; and tying the entire circumference of the masonry structure with the deformed bar.

A novel function-recoverable prefabricated seismic shear wall structure with replaceable components, which includes main structural components, connecting components and replaceable components. All components are connected by bolts or pins. The connections can provide sufficient strength to effectively connect adjacent upper and lower wall panels, or wall panel and coupling beam, together. The replaceable components are installed in the bottom region of the wall and coupling beams, which provide sufficient bearing capacity and stiffness for the building structure under service loads and dissipate seismic energy under the earthquake. The damage concentrates on the replaceable components which could be easily replaced after a strong earthquake so that the function of the building structure could be quickly restored. In addition, the replaceable components with different energy-dissipation mechanisms facilitate the shear wall structure to have multiple seismic fortification lines, and improve the seismic performance of the building structure.
