Lateral load effects on high rise buildings are quite significant and increase rapidly with increase in height. In high rise structures, the behavior of the structure is greatly influenced by the type of lateral system provided and the selection of appropriate. The selection is dependent on many aspects such as structural behavior of the system economic feasibility and availability of materials. The structural performance of high-rise buildings is critically influenced by lateral load-resisting systems, especially under seismic loading conditions. This study investigates the dynamic behavior of a high-rise building equipped with bracings and shear walls when subjected to response spectrum analysis. The primary objective is to evaluate the efficiency of combined structural systems in enhancing the seismic resistance and overall stability of tall structures. A comparative analysis is conducted using structural modeling software to assess parameters such as lateral displacement, inter-storey drift, base shear, and modal behavior. The incorporation of bracings and shear walls is found to significantly reduce seismic response, demonstrating improved stiffness and energy dissipation capacity. The results underscore the importance of integrated lateral load-resisting systems in modern high-rise design, ensuring safety, serviceability, and code compliance under dynamic earthquake loading. In the design of high-rise buildings, ensuring structural stability and safety under seismic loads is a critical concern. This thesis presents a detailed analytical study on the seismic performance of a high-rise building incorporating both bracings and shear walls as lateral load-resisting systems. The building is analyzed using the Response Spectrum Method as per relevant seismic codes to assess its behavior under dynamic earthquake loading. The objective of this study is to evaluate the effectiveness of bracing systems and shear walls individually and in combination in controlling lateral displacements, inter-storey drift, and base shear. A comparative analysis is carried out using structural analysis software, focusing on different configurations of bracing and shear wall placements. This research highlights the importance of hybrid structural systems in optimizing high-rise building responses to seismic excitations and provides valuable insights for engineers and designers aiming to develop safe, economical, and code-compliant structures in seismic-prone regions.
