Abstract - Tall buildings are susceptible to lateral movements and torsional deflections when subjected to earthquake loads. To counteract these effects and ensure structural stability, it's essential to enhance the building's lateral stiffness. Bracing the frame members is a widely employed method to achieve this goal. Bracing systems are designed to minimize lateral deflection by subjecting the frame members to tension and compression forces, akin to a truss system. This project focuses on a comprehensive review of literature concerning the behavior and analysis of various bracing structural systems. The reviewed articles explore different types of bracing systems, including K- bracing, V-bracing, inverted V-bracing, X-bracing, and single diagonal bracing. The consensus from the literature review indicates that implementing bracing systems effectively reduces the adverse effects of lateral loads on tall structures. The proposed project aims to build upon the insights gleaned from the literature review by investigating a mixed bracing system. By combining elements from different bracing configurations, the project seeks to optimize lateral stiffness and stability further. This approach acknowledges the diverse challenges posed by lateral loads in tall buildings and aims to address them comprehensively. Through rigorous analysis and experimentation, the proposed project endeavors to contribute to the body of knowledge surrounding bracing systems in tall buildings. By exploring the efficacy of a mixed bracing system, the project aims to offer practical insights and recommendations for enhancing the structural performance and resilience of tall buildings against lateral forces.
