Exterior Suspended Ceiling Code Requirements
Exterior Suspended Ceiling Code Requirements
(OP)
Looking at a 2' x 4' suspended ceiling panel system placed as a soffit on the exterior of a building. Ceiling failed in high winds. It was obvious there were no uplift struts. Going to court and need to cite all codes discussing the requirements. I found ASTM c-635. i have the 2003 version. Has this changed? Also, need additional codes if any as well as manufacturer's requirements.
Thanks
Thanks

The building code in the area (I'm assuming the IBC) will reference out to ASCE 7 which outlines all the required wind loads to be applied to buildings.
ASCE 7 has specific guidance on wind uplift for both open buildings and for overhangs of roofs. The Components and Cladding forces given in ASCE 7 would be used as the basis for the required uplift pressures on your ceiling. That is all there is to the wind uplift provisions.
If the ceiling failed by getting blow up into the roof (as you suggest - no uplift clips) then the system was obviously not designed properly to account for the wind.
I'm not aware of any other ASTM type documents that would apply here - you have a wind uplift pressure, you have a ceiling, the ceiling needs to account for the uplift.
