Hello,
I am designing a building per Ch. 30 part 2 of ASCE 7-10. I have the MWFRS pressures and the component and cladding (C&C) pressures for the walls and the roof taken directly for Fig. 30.5-1. I'm struggling a little with the roof overhang C&C pressures. My building requires a basic wind speed of 120 mph.
Why doesn't the 'Roof Overhang net Design Wind Pressure' table of Fig. 30.5-1 include a basic wind speed for 120 mph? Why does 30.10 state 'The design wind pressure for roof overhangs of enclosed and partially enclosed buildings of all heights, except enclosed buildings with h <= 160 ft for which the provisions of Part 4 are used, shall be determined from the following equation:...', which seems to contradict the fact that there is a table in Fig. 30.5-1 titled 'Roof Overhang net Design Wind Pressure'.
I looked for errata on this, but I didn't find anything. I must not be understanding something here.
Thanks!
