Rigid Seismic Load Distribution
A accidental eccentricity of 10 percent of the building width at each level has been added to the torsional moments for rigid diaphragm load distribution for seismic loads, to comply with 4.1.8.11 10 (a).
Rigid Wind Load Distribution
In the absence of any provisions to add wind load eccentricity, the torsional moments for wind load distribution now consider only the moments due to asymmetric loading, and no accidental eccentricity.
