Abstract

Lateral forces due to earthquake are the major consideration for design of earthquake resisting structures, these forces can be resisted by various systems like braced frames, shear walls, moment frames, etc. Energy dissipation is one of the most convenient option for earthquake resistance, as it can absorb input energy from earthquake protecting the main structure. Past research revealed that the Buckling Restrained Braces (BRB) are the best type of energy dissipators which is also advantageous of buckling resistance, yielding in both tension and compression. Hence in this research work, the analytical behavior of G + 6 story building using BRB and without BRB have been compared. In this study, X, V, and Y shapes of BRB have been consider to reduce the structural responses. This study also examines the impact of sand, silt and clay soil on the behavior of the building using BRB under earthquake loadings. According to the results, story displacement and drift in case of X BRB with sandy soil shows highest reduction of 56% and 51%, whereas story stiffness yields increase of 54% when compared with other configurations of BRB. It can also be said that the performance of BRB for a building is affected by all three types of soil.
