Example

Determine the nominal moment about the x-axis for the hat section with stiffened compression flange as shown in Figure 6.21. Assume that the yield point of steel is 50 ksi. Use the linear method. The nominal moment is determined by initiation of yielding.

Solution

Calculation of sectional properties. For the linear method, midline dimensions are as shown in Figure 6.22:

1. Corner element (Figure 6.17 and Figure 6.22)

Arc length
