The top chord also has specification IL 4 x 3 x 3/8x 7(e). This means it has five clip angles attached, andeach of them is an angle 4 inches by 3 inches by 3/8 inchthick and 7 inches in length.The gusset plate (a) on the lower left of the view islabeled PL 8 x 3/8 x 1´-5(a). That means it is 8 inchesat its widest point, 3/8 inch thick, 1 foot 5 inches long atits longest point.The bottom chord is made up of two angles 2 1/2 x2 x 5/16 x 10´-3 7/16, which are connected to gussetplates a and b, and two more angles 2 1/2 x 2 x 1/4 x10´-4 1/8, which are connected to gusset plate b andcontinue to the other half of the truss. Two more anglesare connected to gusset plates c and b on the top andbottom chords; they are 2 1/2 x 2 x 1/4 x 2´- 10 1/2. Theother member between the top and bottom chords,connected to gusset plate b and the purlin gusset d, ismade up of two angles 2 1/2 x 2 x 1/4 x 8´-5.View A also shows that most of the rivets will bedriven in the shop with the exception of five rivets in thepurlin gusset plate d and the two rivets shownconnecting the center portion of the bottom chord,which is connected to gusset plate b. These seven rivetswill be driven at the jobsite. Figure 7-8 showsFigure 7-8.—Riveting symbols.7-9
