Researchers have combined passive control systems of differing stiffness with each other to provide multistory passive control systems. Each system absorbs and dissipates the applied energy according to its stiffness. This study investigates the multistory control system with the modern pipe in pipe passive damper, and combining them with braces, which are able to change stiffness and absorb energy under various loads to reduce seismic structural vibrations. Their performance in 5, 10 and 15 story 3D steel structures on type 1, 2 and 3 soil was evaluated with nonlinear time history analysis and referred to as the structure’s seismic responses. Results showed that using a combination of dampers and braces in 5, 10 and 15 story steel structures can be a suitable substitute for traditional bracing systems. For example, using pipe in pipe dampers instead of dual structures in 5, 10 and 15 story structures on type 3 soil reduced base shear by 45%, 51%, and 55%, and roof acceleration by 39%, 35% and 50%. Compared to dual structures, a combination of dampers in lower stories and braces in higher stories on type 3 soil reduced base shear by 36%, 36% and 46%, and roof acceleration by 38%, 32% and 41% in the 5, 10 and 15 story structures.
