C&C Wind Loads on Roof Overhang per ASCE 7-10 Figure 30.5-1
Asce 7-10 Chapter 30 Pdf 9/19/2019 I've been tasked with designing a foundation system for a 60' tall, 50,000 gallon ground-support tank used for liquid storage. My firm has had a older 'rule of thumb' reference on tank seismic design from IBC 2000. Lesson: Basic Wind Loads ASCE 7-10 Page 1 of 21 Basic Wind Loads ASCE 7-10 Developed by John Herrick Course Description If you design buildings you have to understand wind forces and how to prepare for them. One of your tools in designing for wind loads on structures, including roofs, walls, and windows, is the ASCE 7 Manual, Chapter 28.
C&C Wind Loads on Roof Overhang per ASCE 7-10 Figure 30.5-1
Asce 7-10 Chapter 30 Pdf
The building which is used as headquarter for police operation, is 30 m x 15 m in plan as shown in the figure (enclosed), and located right on the Gaza Beach (flat terrain). Note: Use a basic wind speed of 100 Km/hr and ASCE 7-10 Directional Procedure. A noticeable modification was the chapter reorganiza - tion for wind design. The 2005 edition addressed wind design in one chapter, Chapter 6, while the 2010 edition has six chapters, Chapters 26 to 31. The chapter relevant to roof systems is Chapter 30, which addresses compo - nents and cladding. In addition, ASCE 7-10 provides six.
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!
