Abstract

Skyscrapers and other large buildings are being constructed worldwide these days. Because wind is so dynamic, it plays a major part in the design of these towering structures. The placement and height of such structures have a major impact on how wind affects them. The comparable static approach is used in this work to evaluate wind loads on structures with variable aspect ratios attained by altering the number of bays. The 2015 edition of IS 875 (Part 3) governs the evaluation of wind loads on different kinds of constructions. In particular, this study examines how wind loads affect buildings with varying aspect ratios, or the H/B ratio where, H is the building overall height and B is its width. The study's models are divided into groups according to the buildings' aspect ratio and storey height. To find out how wind load affects gravity load, frame models with aspect ratios of 1, 2, and 3 are examined. The study also investigates the effects of changing the number of storeys 10, 20, and 30 on the wind load on building height. ETABS software is used to idealize and evaluate all frame models as 3D models. The examination of displacement fluctuations, storey drift, and shear force helps to comprehend how the frames behave when subjected to wind loads.
