Abstract: Now a days steel based structures are more conveniently used in comparison with RCC based structures thanks to its ductility behaviour. The ductility and energy dissipation capacity are important for a structure to resist seismic force. To boost the energy dissipation capacity of a steel framed structure, bracing were used. Here G+14 story building steel framed structure were selected for investigation. Thereon structures energy dissipation capacity were improved by introducing the X bracing, V bracing and zipper bracing. STAAD PRO and SAP2000 are employed for the analytical analysis. The relation between the performance of the different braced framed structure is made through pushover analysis. The criteria acclimatized with understanding the seismic efficiency of the casings are performance points, base shear capacity and roof displacement. The arrangement of the bracings on the edge structure has increased the base shear conveying limit, the performance point and reduced the displacement of the roof for all steel frames.
Keywords: Base Shear, Bracings, Pushover analysis, Roof displacement, Performance point.
