Joints - The Behaviour and Design of Steel Structures to EC3 - page 431

9.11 Unworked examples

9.11.1 Example 10 - bolted joint

Arrange and design a bolted joint to transfer a design force of 800kN from the
inclined member to the truss joint shown in Figure 9.23a.

9.11.2 Example 11 - tension member splice

Arrange and design the tension member splice shown in Figure 9.23b so as to
maximise the tension resistance.

9.11.3 Example 12 - tension member welds

Proportion the weld lengths shown in Figure 9.23c to transfer the design tension
force concentrically.

9.11.4 Example 13 - channel section bracket

Determine the design resistance Q of the fillet welded bracket shown in
Figure 9.23d.

9.11.5Example 14 - tee-section bracket

Design the fillet welds for the bracket shown in Figure 9.23e.
