The thickness of the plate is to be determined from

14Mpiu Y 0.90Fy where Mplu is the moment per unit width of critical section in the plate. Mplu is to be determined by assuming that the portion of the plate projecting beyond the critical section acts as an inverted cantilever loaded by the bearing pressure. The moment calculated at the critical section divided by the length of the critical section (i.e., B) gives Mplu. Moderate Eccentricity, N/6 < e < N/2

For plates subjected to moderate moments, only portion of the plate will be subjected to bearing stress (Figure 4.31). Ignoring the tensile force in the anchor bolt in the region of the plate where no bearing occurs and denoting A as the length of the plate in bearing, the maximum bearing stress can be calculated from force equilibrium consideration as
