Abstract [English]

This paper presents a comparative study on the effectiveness of various bracing systems in multi-story steel buildings, a critical aspect of structural design given the significant influence of lateral loads. While bracing systems are globally recognized as a superior solution for resisting lateral forces, their comparative performance across different configurations requires detailed investigation. The study models a 20-story steel building with a uniform layout, incorporating four distinct bracing types: knee, Z, X, and V bracings along with bare frame model. Using the commercial software Staad Pro V8i for analysis, the comparison measures the crucial performance indicators such as top story displacement, and the axial force, bending moment, and shear forces experienced by columns. All structural sections are designed in accordance with IS 800:2007, integrating the Limit State Design philosophy. The findings aim to demonstrate the impact of these different bracing configurations on the structural response of multi-story steel buildings under lateral loads.
