EVALUATING THE STRUCTURAL PERFORMANCE OF BUILDING FRAME AND DUAL FRAME SYSTEM INCORPORATING SHEAR WALLS

Abstract

As cities grow and more high-rise buildings are constructed in earthquake-prone areas, ensuring these structures can withstand seismic forces has become a top priority. In this study, we used ETABS software and the Finite Element Method to analyze and design a G+7 building, focusing on its performance under static and earthquake loads based on UBC-97 standards. We compared two structural systems—a building frame and a dual frame system—to understand how changes in dimensions, material strength, and the placement of shear walls affect the building's safety and stability. The findings showed that positioning the shear wall at the core of the building provides the best results, reducing story drift and displacement while maintaining overall safety. This research emphasizes the importance of smart design choices and modern tools in creating safer, earthquake-resistant buildings that meet the challenges of urban growth.
