- The document analyzes the seismic performance of eccentrically and concentrically steel braced steel structures through equivalent static analysis in STAAD.Pro. - Results show that braced structures perform better than unbraced structures, with braced structures experiencing lower lateral displacement and storey drift. Cross braced and concentrically braced frames performed the best with least displacement. - Braced structures are more effective at resisting seismic loads and dissipating seismic energy compared to unbraced structures. The use of bracing systems improves the lateral stiffness and capacity of steel structures.
