Irregularity

The document compares the mass of different levels of a building to determine if any mass irregularities exist. It finds that levels 2 through 4 do not have mass irregularities when compared to adjacent levels. However, it does find a mass irregularity between levels 5 and the roof. It also analyzes the building for a soft story condition and determines that one does not exist based on a calculation of drift and story stiffness.
