The Impact of Different Shear Wall Structure Position on Symmetric and Unsymmetric Tall Buildings

Abstract

Abstract: The shear wall is a structural component used to withstand lateral stresses. These walls will absorb shear stresses and avoid construction site relocation and subsequently devastation. For instance, if the shear walls are not constructed, we cannot expect the structure to exhibit acceptable tensional behavior. The contribution of the remaining structural elements to the bending moment, shear force, torsion, and axial force, as well as the final design of all structural components, are also impacted by shear wall. Over the last two decades, there has been an almost exponential increase in the building of towering skyscrapers above 150 meters in height. Numerous identical buildings have been constructed across the Middle East and Asia, and many more are now being planned or constructed. Buildings taller than 300 meters provide significant engineering challenges, particularly in terms of structural and geotechnical design. Wind analysis is crucial for tall constructions. Numerous studies have explored the structural behavior of tall buildings with SSI by considering a range of criteria, including foundation type, soil conditions, lateral loads. The current study presents G+18-story rectangular building and a asymmetric building with a 3 m floor-to-floor height was evaluated in ETABS in zone III. The structure's resistance to static and dynamic wind and seismic forces has been studied using shear walls in various locations, such as without shear walls, shear walls in the outer center, and shear walls at the corners. The results obtained are compared in the form of storey drift, joint displacement and storey drift. The research indicates that the shear wall at outer Centre with firm soil has the best response compared to without shear wall and shear wall at corner condition for symmetrical building. And for asymmetrical building shear wall at corner condition has best response compared to without shear wall and shear wall at outer centre condition.
