The program calculates and displays the out-of-plane forces for structural walls from ASCE 7 12.11.
The out-of-plane force wall force is calculated using 12.11.1 and the self-weight of the wall as input in the Load Generation dialog.
The wall anchorage force is calculated using Eqn. 12.11-1 in section 12.11.2.1. The length used for the ka factor in Eqn. 12.11-2 is the shear line length (including any non-shear walls and openings or gaps within the line, but not gaps at between the end of the line and the end of the floor or ceiling diaphragm).
For rigid diaphragms, the height factor given in the penultimate paragraph in 12.11.2.1 uses the eave height as roof height .
The resulting values are shown in Elevation view for each wall line.
