(Tier 2: Sec. 4.4.2.7.2) <br />N/A GYPSUM WALLBOARD OR PLASTER SHEAR WALLS: Interior plaster or gypsum <br />wallboard shall not be used as shear walls on buildings over one story in height with the <br />exception of the uppermost level of a multi-story building. (Tier 2: Sec. 4.4.2.7.3) <br />C NARROW WOOD SHEAR WALLS: Narrow wood shear walls with an aspect ratio greater <br />than 2—to-1 for Life Safety and LS-to-I for Immediate Occupancy shall not be used to resist <br />lateral forces developed in the building. Nanow wood shear walls with an aspect ratio grcater <br />than 2-to-1 for Immediate Occupancy shall not be used to resist lateral forces developed in the <br />building in levels of low seismicity.
