Abstract:
Structural asymmetry is a common challenge in modern engineering, particularly in buildings and frameworks where irregular geometry leads to uneven load distribution and increased susceptibility to lateral forces. This study presents a comprehensive analytical approach to evaluating the behavior of unsymmetrical structures by incorporating various bracing configurations to enhance stability, minimize displacement, and improve overall structural performance. This study aims to assess the impact of different bracing systems, including X-bracing, V-bracing and K-bracing, on the structural response under static and dynamic loading conditions. Using ETABS to study models and analyzes multiple structural configurations to determine the most effective bracing arrangement. Key performance indicators such as story drift, base shear, lateral displacement, inter-storey drift ratio, and stress distribution are examined to understand the influence of bracing on the stiffness and strength of unsymmetrical frames. The results highlight that strategic bracing placement significantly enhances lateral rigidity and improves load-bearing capacity in asymmetrical structures. In this study, a G+24 high-rise structure with an unsymmetrical plan is designed and analyzed under seismic loading conditions in Zone-III, as per the Indian Standard (IS) code. To enhance structural stability and control various performance parameters, three different bracing configurations K-bracing, X-bracing, and V-bracing are incorporated. The modeling and analysis of the structure are carried out using ETABS software, allowing for a detailed evaluation of the bracing effects. The results are then compared to assess the influence of each bracing type on the overall performance of the unsymmetrical structure. Future studies should focus on optimizing and hybridizing bracing systems to balance strength and flexibility. X-bracing, showing the best performance, should be tested under dynamic and seismic conditions. Use of advanced materials, experimental validation, and consideration of architectural impact are recommended. These systems also hold promise for retrofitting and can benefit from intelligent design tools.
