Thank you to all that responded. I wanted to let you know that a response was received from the ASCE 7 Wind Subcommittee. They indicated that for the hipped end in the case where the wind is parallel to the ridge the bottom section of the table provided in Fig 27.3-1 (Parallel to Ridge for all θ) should ...

Hi Keith MacBain, Thanks for the feedback. In this case I am the software developer for the Wind software and that's the reason I'm trying to get clarity. I can see both sides of the argument and am hoping to get a definitive answer. Mr. Ronald Hamburger from the ASCE 7 wind committee frequently responds ...

This question really applies to all ASCE 7 versions. The MWFRS roof pressure Coefficients are determined from Figure 27.3-1. In the case where the wind is parallel to the ridge, and the hipped end has a slope of ≥ 10°, do we consider the hipped end "Normal to Ridge" or "Parallel to Ridge"? For example, ...

Dwayne, You are referencing ASCE 7-16 Fig 30.3-2D, and I agree the value of GCp is -1.8 for the roof and -2.6 for the overhang. If you refer to ASCE 7-22 Fig 30.3-2D, I think it sheds some light on this topic. In ASCE 7-22 Fig 30.3-2D they removed the overhang chart and instead refer you to Section ...

Hi Dwayne, My company develops ASCE 7 wind software, and so we go through the standard in quite a bit of detail. I don't ever recall anything in the standard that indicates that the size of an overhang is a consideration, I have always interpreted it as any overhang uses the Overhang figure. Regards, ...
