Abstract

Objectives: To study the effect and variation of wind pressure with the shape, rounding of the corners and height of the structure. Methods: Aerodynamic approach is architecture is the extreme approach in the design of tall buildings. In the present thesis, multistory buildings of 40 storey, 60 storey and 80 storey were modelled for different shapes of structures i.e. Rectangular structure, Rectangular structure with rounded corners, Square structure, Square structure with rounded corners, Circular structure and Elliptical structure. Findings: The influence of height and shapes on gust loads and its effects on the response of the structure are studied in the present case. The analysis of the building has been carried out using standard commercial software (STAAD PRO) and the estimation of wind loads is done by Indian standard code IS-875(Part-3). The effect of rounding of the corners of tall structures is studied through computational fluid dynamics (CFD) on pressure distribution on the surface of the structure. Novelty: Standard software fluent is used for CFD analysis.
