ASCE 7-05 Wind Loads Question ASCE 7-05 Wind Loads Question Decartes (Structural) (OP) 17 Apr 12 18:06 Does anyone know, what part of ASCE 7-05 addresses/is applicable to the design wind load on an outdoor structure w/ a Gable Roof supported by one column? You heard me correct "one" column. RE: ASCE 7-05 Wind Loads Question MiketheEngineer (Structural) 17 Apr 12 18:18 I would probably use a "sign post" analysis - just assume that the gable is a big sign?? RE: ASCE 7-05 Wind Loads Question Decartes (Structural) (OP) 17 Apr 12 18:37 @MiketheEngineer, how would you then account for the uplift/downward pressures on the roof? Do you think ASCE 7-05, 6.5.13 or 6.5.15 would apply? RE: ASCE 7-05 Wind Loads Question JAE (Structural) 17 Apr 12 23:59 I think the shape of the roof is more important than the number of columns. RE: ASCE 7-05 Wind Loads Question RobertHale (Structural) 18 Apr 12 08:04 I would agree with JAE. The Cn values account for the aerodynamic shape of the roof. The negative values of Cn will generate your uplift. I would think it is important to keep the cases distinct to capture the overturning moment at the top of the column, as well as applying Figure 6-9 to generate torsional moments on the column. RE: ASCE 7-05 Wind Loads Question Decartes (Structural) (OP) 18 Apr 12 22:06 @ JAE and RobertHale, I agree with both of you, ASCE 7-05 Sect. 6.13 applies, because the roof of the open structure is a critical design feature. Thanks to all who replied so far, I really appreciate it.
