## Remarks

・AI：『influence area, in square meter (ft2). The influence area AI is four times the tributary area for a column, two times the tributary area for a beam, equal to the panel area for a two-way slab, and equal to the product of the span and the full flange width for a precast T-beam.』(Reference[1])
・L：『reduced design live load per square meter (ft2) of area supported by the member.』(Reference[1])
・Lo：『unreduced design live load per square meter (ft2) of area supported by the member』(Reference[1])
・『The reduced live load shall not be less than 50 percent of the unit live load Lo for members receiving load from one level only, nor less than 40 percent of the unit live load Lo for other members.』(Reference[1])
