Comparative Study Of Different Bracing Systems On G+29 Steel Frame Building

Abstract

The resistance to the lateral loads from wind or from an earthquake is the reason for the evolution of various
structural systems. Bracing system is one such structural system which forms an integral part of the frame. Such a
structure has to be analysed before arriving at the best type or effective arrangement of bracing. This project is about the
efficiency of using different types of bracings and with different steel profiles for bracing members for multi-storey steel
frames. ETABS software is used to obtain the design of frames and bracing systems with appropriate steel section
selection for beams, columns and bracing members from the standard set of steel sections. A three dimensional structure
is taken with 5 horizontal bays of width 5 meters, and 30 stories is taken with storey height of 3.5m. The beams and
columns are designed to withstand dead and live load only. Wind load and Earthquake loads are taken by bracings. The
bracings are provided only on the peripheral columns. Maximum of 4 bracings are used in a storey for economic
purposes. In this study, an attempt has been made to study the effects of various types of bracing systems with respect to
displacement.
