WIND PRESSURE AND VELOCITY PATTERN AROUND  N PLAN SHAPE TALL BUILDING-A CASE STUDY

The principal aim of this case study includes the determining of wind pressure co-efficient and wind velocity analysis of N-plan shape tall building using k-ε method. The wind angles varying from 0° to 180° at 30° interval scale of 1:300 and terrain category 2. A square plan with same area compared with the N-shape model also validated with different codes AS/NZS: 1170.2 (2002), ASCE/SEI 7-10 (2010), BS: 6399-2 (1997), EN: 1991-1-4 (2005) and IS 875 (part 3) (1987). The wind velocity and force coefficients around this model at different faces are also discussed here.
