The efficiency of the RC core system in buildings that are taller than 35 to 40 story is modestly reduced. In these structures, connecting two towers with a bridge can be considered as one of the solutions for controlling displacement and also energy dissipation. This paper examines the types of energy needs in high-rise buildings of 40 and 60 floors, each of which has two reinforced concrete core of the same height with a truss bridge. The trusses of the bridge are made by buckling restrained elements. Initially, this structure is designed using the response spectrum analysis method according to the valid codes. This paper examines the types of energy needs in high-rise buildings of 40 and 60 floors, each of which has two reinforced concrete core of the same height with a truss bridge. The trusses of the bridge are made by buckling restrained elements. Initially, this structure is designed using the response spectrum analysis method according to the valid codes. On average, in extended plastic hinge approach the core share is about 48%, and the share of the bridge with buckling restrained members is about 52% in term of non-elastic energy, and these values are 34% and 66% in the single plastic hinge approach. Studied structures, connecting two towers with a bridge can be as one of the solutions for controlling displacement and also energy dissipation.
