    ponding, length of a cantilevered member for Cp calc

    I have an existing building with a spliced beam system supporting joists and metal deck. The bays are 40'x40'. The roof slope is 3/16" per foot. I am checking for ponding instability. The formula for Cp in AISC is Cp=32xLsxLp^4/10^7xIe. The splices are 5'6". For the beams that cantilever...
