ASCE 7-10 Wind Provisions
ASCE 7-10 Wind Provisions
(OP)
I am studying for the lateral portion of the SE exam and I am confused with the ASCE 7-10 wind provision chapters 26-28. I'm in the bridge world so I don't deal with 7-10 but I was somewhat familiar with 7-05 and it's all different than what I was used to. What is the difference between the 3 chapters? It looks like different procedures, but how do you know which chapter you need to be looking in to determine the correct wind pressure?






RE: ASCE 7-10 Wind Provisions
Chapter 26 is always used - simply provides for determining the base wind pressure.
Main Wind Force Resisting System Wind Forces (MWFRS)
Chapter 27 is a directional procedure for Main Wind Force Resisting systems - MWFRS (i.e. for design of your floor/roof diaphragms and and main wind braces or moment frames)
Part 1 is the general/main procedure for all buildings - we typically use this.
Part 2 is a simplified procedure for simple buildings < 160 ft. in height - we don't typically use this method
Chapter 28 is a MWFRS method for low rise buildings - we don't use this.
Chapter 29 is a section for MWFRS on rooftop equipment, chimneys, tanks, etc.
Components and Cladding Wind Forces
Chapter 30 is for C&C wind forces
Part 1 is the general section for Low-Rise Bldgs
Part 2 is for Low-Rise Bldgs. but a simplified method (we don't use this)
Part 3 is for buildings > 60 ft.
Part 4 is a simplified method for buildings <= 160 ft. (we don't use this)
Part 5 is for open buildings
Part 6 is for rooftop equipment, chimneys, tanks, etc.
Chapter 31 - wind tunnel procedure used for larger, odd shaped buildings.
