Day by day as the amount and intensity of earthquakes are increasing, the need for earthquake resistant building is also increasing. But always designing strong column and weak beam is not solution because it will definitely increase cost of construction. This paper presents a summary of current practice and recent developments in the application of passive energy dissipation systems for seismic protection of structures. Major topics that are presented include design of Buckling Restrained Braces (BRB), factors influencing Design Parameters of BRB on its performance and the use of MATLAB for evaluating the same. In recent years, Buckling Restrained Braced Frames (BRBFs) are widely used as seismic force-resisting systems due to their significant ductility and energy dissipation capacity. Buckling-restrained braces are braced frame structural system components that do yield in both tension and compression, thus acting as energy dissipators. They do not only stiffen their parent structures but reduce drift too. In this study, parameters affecting performance of Buckling Restrained Brace such as Stiffness, Material of Core, Core Member Length, and Bracing angle were analyzed. MATLAB being a high-performance language for technical computing, it integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Therefore, it is used for evaluation of potential drift and design of Buckling Restrained Brace in early stages of design and later the results obtained on MATLAB were verified on another structural analysis software ETABS. A numerical example is also provided to understand the concepts better.
