Energy dissipation capacity and seismic performance of steel moment resisting frame with hybrid damping system along with buckling restrained brace is investigated and an innovative approach of design of energy dissipating system is recommended. The nine storied structure is analyzed by nonlinear time history analyses using seven time histories and scaled to achieve a set of results and then compared the various possibilities. The multi-linear elastic and plastic links are used to model energy dissipating devices with the help of SAP 2000. The various results such as story displacement, story drift, roof drift, base shear and roof acceleration of steel moment resisting frame are compared with the system after installation of energy dissipaters in the same moment resisting frame that means a dual buckling restrained brace with steel moment resisting frame system and a dual hybrid damping system with steel moment resisting frame system. It was expected that the system will work in individual phases as earthquake intensity will go on increasing and in end results, the models have shown the same. It also has got depicted that the energy dissipation of the systems gets improved after installation of hybrid damping systems. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
