Consider a WT12x51.5 A992 section subjected to shear forces Centroid (i) With the thin-wall assumption the T section consists of the two lines passing through the center lines of the web and flange as shown. Using this two line model compute centroid and x and y moments of inertias. Note that these values will be slightly different than those given in the AISC tables for this section. The tabulated values are more accurate and should be used for design. However...
