Question 2
(a) A simple circular hollow section (CHS) tubular K-joint in a steel structure, subjected to balanced
axial loading, is illustrated in Figure 2a. Determine the maximum hot spot stress at the joint
intersection of the chord and the loaded brace B.
(b) The steel structure is installed in the seawater with cathodic protection. Determine the number of
stress cycles to failure based on the maximum hot stress range obtained in part (a). Use the
NORSOK standard. (Refer to S-N curves for tubular joints in air environment and seawater with
cathodic protection).
(c) Estimate the number of load repetitions required to induce fatigue failure in the tubular joint, based
on the load history provided in Figure 2b. The nominal yield and ultimate tensile strength are 355
N/mm² and 510 N/mm², respectively. Assume a damage limit of 1.0. Use the Modified Goodman
formulation to determine the equivalent completely reversed stress.

- 30 20 10 Stress N/mm² 0 -10 -20 -30 Time Question 1 A Grade S355 steel member, which forms part of the structural framework supporting a storage tank in a warehouse, is subjected to various loads, as shown in Figure 1. The yield and tensile strength of the steel member are 355 N/mm² and 510 N/mm², respectively. The steel member is subjected to axial tension due to its self-weight and appurtenances of 40.0kN. The 10.0kN storage tank is positioned 1.0 m from the centreline of the steel member, and it experiences a fatigue load range of 5.0kN. The steel member is a fillet welded built-up section that comprises two flange plates (100mm x 20mm) and a web plate (250mm x 10mm) as depicted in Section A-A. The leg size of the weld is 8 mm.
