Low Rise Loads on Hip Roof

Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 10.0 and may not reflect current behavior

The program now allows you to optionally implement ASCE 7-10 figure C28.4-2 for wind loads on hipped roofs. Note that with this model, for both load case A and load Case B, case A coefficients are used, so that Case A and Case B are identical in the transverse-to-ridge direction.

1. Setting

   An option in the Load Generation input dialog allows you the choice of using figure C28.4-2 or treating the end panel as a transverse side panel as Version 9 does.

2. Note 8 Loads

   The loads that are generated due to Note 8 for distances greater than ½ the horizontal dimension of the building are created for this method.

3. Equal Slope Restriction

   The restriction that hips on opposite ends of the roof must have equal slopes is dropped for this method.

4. Warning Message

   The warning message that we treat hip ends as side panels does not appear if the C28.4-2 method is chosen.
