Thickness Adjustment Tables for Popular Designs
Thickness adjustments for alternate size steel beams and columns are possible using the proprietary thickness data in many fire test designs and by using the generic thickness adjustment equations in the ULI Fire Resistance Directory. For your convenience we have calculated the available adjusted thicknesses for the following popular designs:
