Part 5: Detailed Design of Trusses 5 - 49 component members of the chord. The gussets are, therefore, either welded or bolted on the chords. The diagonals and posts are connected to the gussets, usually by bolting. When the chords are made of IPE or HEA/HEB sections, the most common connection method is also to use a welded gusset plate on the chord. The gusset plate is attached to the flange when the section is upright (vertical web), and to the web when the section is flat (horizontal web). (a) Bolted gusset in the space between double angle chords, truss members in bolted double angles onto gusset (b) Welded gusset on HEA chord flange, double angle truss members bolted to gusset (c) Gusset welded to web of flat IPE chord Figure 5.5 Truss connections on chord When the chord sections are flat, it is also common to use IPE or HEA truss members with the same depth as the chords and to connect them by double gussets, one on each flange. An alternative solution is to design a welded connection without gussets, as shown in Figure 5.6.
