Wall Height at Gable Ends for Hold-down Force Calculation (Bug 2465)

In order to include the portion of an end wall that is beneath a gable end as part of a shearwall, for the purpose of hold-down force calculations, the program now calculates the wall height at a gable end as being the distance from the base of the wall to the height of the sloping roof at the end of a wall segment.

The average of the heights at both ends of the segment under a gable end is used as the moment arm h in the hold-down force calculation R = vh, where R is the hold-down force and v is the shear per unit foot directed horizontally. Previously the height of the upper level was used as the wall height. Refer to the Shearwalls Help topic Hold-down Forces for further explanation.
