ABSTRACT

Earthquake forces on structure are of great concern to the engineers. To minimize the effects of an earthquake and lateral loads, the steel braced frames are used. It is one of the systems which plays an effective role in resisting the lateral loads the new type of bracing system called buckling restrained braces are introduced to overcome the drawbacks of conventional bracing system. The project work is to study buckling restrained braces. The analysis is done using MATLAB. In the present study, a code for a building model is developed to analyze the behaviour of the structure without BRB. Time history method is used to determine the dynamic response of the structure. A mathematical model was created to perform modal time history analysis. Time stepping was performed using Newmark’s Beta modified for linear acceleration. The response parameters such as Base Shear, Story displacement, Time period, Inter-story drift are evaluated to study the structural performance. The same model results are validated in ETABS v16. Further, a code will be developed for a building structure with BRB to compare the response of both structures.
