[1]1607.12.1 Basic uniform live load reduction.
Subject to the limitations of Sections 1607.12.1.1 through 1607.12.1.3 and Table 1607.1, members for which a value of KLLAT is 400 square feet (37.16 m2) or more are permitted to be designed for a reduced uniformly distributed live load, L, in accordance with the following equation:
(Equation 16-7)
[1]For SI:
where:
L = Reduced design live load per square foot (m2) of area supported by the member.
Lo = Unreduced design live load per square foot (m2) of area supported by the member (see Table 1607.1).
KLL = Live load element factor (see Table 1607.12.1).
AT = Tributary area, in square feet (m2).
L shall be not less than 0.50Lo for members supporting one floor and L shall be not less than 0.40Lo for members supporting two or more floors.
