Live load reduction<br />
Since large members are unlikely fully loaded,<br />
ASCE 7 allows live load reductions<br />
(except for public spaces <strong>and</strong> LL ≥ 100 psf):<br />
For members supporting ≥ 600 sq. ft.<br />
Reduction shall not exceed<br />
50% for members supporting 1 floor,<br />
60 % for members supporting 2 or more floors
