Wind Pressure and Velocity Around Stepped Unsymmetrical Plan Shape Tall Building Using CFD Simulation- A Case Study

This paper presents the study on wind pressure, velocity and force coefficient analysis done in ANSYS software using CFD simulation (k-εmodel) for stepped unsymmetrical plan shape tall building for a wind incidence angle ranging from 0 to 360 with an interval of 45 in the ratio of 1:300. The study aims at establishing the similarity between the codes like IS 875-(PART 3)(1987), AS/NZS: 1170.2 (2011), ASCE: 7-02 (2002), and the experimental rectangular model. The flow patterns around the building are considered for different heights and for different wind angles which help to understand the difference in pressure variation for designing purpose of the building.
