The built$-$up section is composed of four $L43\frac{1}{2}$ angles, two $9xx\frac{1}{\frac{?}{?}}{2}^{\text{'}\text{'}}$ plates for the flange, and one $8"x\frac{3}{8^{\text{'}\text{'}}}$ plate for the web. Note that the total effective depth of the section is $9^{\text{'}\text{'}},$ and the angles are oriented horizontally at the longer leg. Also, the following external loadings applied to this built$-$up section are shown below.
