Abstract: A coupling structure is arranged between a first boundary member and a second boundary member. The coupling structure mainly includes a main coupling unit, a reinforcement unit, and a concrete layer, and the reinforcement unit is arranged on the main coupling unit and surrounds an intermediate area of the main coupling unit, and the main coupling unit and the reinforcement unit are both embedded in the concrete layer. The coupling structure can solve the current design difficulties of short columns and short beams and has excellent seismic performance and higher construction efficiency.

Abstract: A shock damper includes a damper body installed in the frame of a structure and adapted to absorb earthquake shocks, and braces adapted to support the damper body in the frame of the structure, the damper body having a horizontal top plate, a horizontal bottom plate, and a vertical connecting device connected between the horizontal top plate and the horizontal bottom plate, the connecting device being a shaft formed of any of a variety of cross sections, or a plurality of plates of any of a variety of profiles.
