Title Appendix B Worked Example: Design of a truss node with gusset 8 of 44 5 - 87 3. Angles to gusset bolted connection Three shear connections are designed as Category C. These connections are shown in Figure B.8. 320 260 260 16 41.3° 42° 15 N1 N2 N3 Figure B.8 Angles to gusset bolted connections This connection is composed of two back-to-back double-angle diagonal members (N1 and N3) and a single angle post member (N2). The internal forces in the truss members are: N 1,Ed = 406,9 kN tension axial force N 2,Ed = 2,6 kN tension axial force N 3,Ed = -609,4 kN compression axial force 3.1. Basic Data Material data (except bolts) Steel grade S355 Yield strength f y = 355 N/mm 2 Ultimate tensile strength f u = 510 N/mm 2 EN 1993-1-1 Table 3.1 Gusset plate Thickness t g = 15 mm Length L g = 580 mm Width H g = 260 mm Angle members N1 two equal-leg angles L150  150  15 N2 one equal-leg angle L100  100  10 N3 two equal-leg angles L150  150  15
