Thanks WebJan 17, 2013 · You reduce the allowable bending stress if the unsupported length of the compression flange requires it. In this case from 0.6 F = 0.6 (36.0 ksi) = 21.6 ksi, down to 10.9 ksi. This doesn't enusre that a thin frange has the strength to withstand a concentrated load like a small trolley. immigration sponsorship letter sample
