CHAPTER 6 WIND LOADS Outline 6.1 General 6.1.1 Scope of .
6.1.3 buildings for which particular wind load or wind induced vibration is taken into account. 6.2 Horizontal . wind load for structural frames is calculated from the product of velocity pressure, gust effect factor and projected .. across-wind and torsional directions at top of building b (m): projected width of member f (m): rise. 1f (Hz): The smaller of L f and T f. D f , L . with light weight because the deflection or oscillation-induced wind force due to mean wind pressure seems to make the .
