COLD FORMED STEEL GCP VALUES WITH MONOSLOPE > 30 DEGREES
COLD FORMED STEEL GCP VALUES WITH MONOSLOPE > 30 DEGREES
(OP)
Hi, I have a question regarding pressure coefficients in ASCE 7-05.
The code only denotes for mono-sloped roofs with a slope less than 30 degrees but I have a roof with a mono-slope @ 45 degrees. (enclosed).
Is my only option to use wind loads for open monosloped roofs.
Where am I to get these Gcp values in order to calculate my wind pressures.
Regards

1. Keeping the same roof zones sizes as the 30 degree chart
2. Double -GCp for zone 3
3. Maybe 1.5 times -GCp for zones 1 and 2 (tough because the lower eaves may see lower uplift at 45 deg)
4. 1.5 to 2 times +GCp for all zones
