Wind flows smoothly around a round object (Fig. 1). Wind creates more force and turbulence around a flat object (Fig 2); this increased force requires a significant increase in tower structural capacity just to support the tower itself, in addition to the capacity required to support the antennas and lines. COMPARATIVE ANALYSIS OF STEEL IS 875 (part 3):1987 and IS 802 (Part 1:Sec1)-1995 are referred to estimate wind loads on the towers.
