Abstract:
This study examines the performance of shear wall in tall buildings under wind load bearing in mind the effects of different opening areas on the system reaction against this force. Shear walls play important roles in offering lateral resistance to tall buildings especially in their resistance to forces arising due to the wind pressure. The location and gap of openings in these walls may however greatly influence their behaviour in response to the wind loads. The paper uses a set of numerical cases of the behavior of shear walls in high-rise buildings with a different opening size, both small and large. The model has emphasized the use of main performance metrics like lateral displacement, shear, and torsion upon the influence of diverse situations of the wind load. Evaluation of the influence of various opening sizes will help the research center to identify the most effective techniques of maintaining structural integrity and stability of high-rise buildings during windy situations. The findings suggest that enlargement of the sizes of openings in shear wall results in the decrease of total effectiveness of this type of shear wall, especially with regards to lateral loads. Higher openings reduce the shear resistance of walls and this leads to more displacement and poor stability. It is also presented in the study that strategic location and size of openings are key to ensuring that the structural elements of shear walls are not compromised in terms of strength. The study revealed that incorporating shear walls significantly improved the seismic performance of structures. The maximum storey displacement in the bare-frame model was 289.07 mm, which reduced by 45.2% with solid shear walls, and by 42.8% and 20.3% with 30% and 60% wall openings, respectively. Storey drift also showed similar trends, decreasing by up to 55.9% with solid walls. The bending moment dropped by 82.2% with solid shear walls, and by 54.2% and 36% with 30% and 60% openings, respectively. Shear force reduced by up to 48.3%, while base shear increased slightly (up to 4.7%) with solid walls and surged by 52.9% in the 60% opening model, indicating higher stiffness leads to greater load attraction. Overall, shear walls, even with moderate openings, significantly enhance structural stability.
