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.
