Fatigue. Design procedure for welded hollow-section joints. Recommendations. | Status: Under review, Current

1 Scope

1.1 General

This International Standard gives recommendations for the design and analysis of unstiffened, welded, nodal joints in braced structures composed of hollow sections of circular or square shape (with or without rectangular chord) under fatigue loading. This International Standard applies to structures:

1. a) fulfilling quality requirements for hollow sections (see Annex A);
2. b) complying with recommended weld details (see Annex B);
3. c) employing permitted steel grades (see 1.2);
4. d) having hollow section joints (see 1.3);
5. e) having either
   1. 1) square or rectangular hollow sections with a thickness between 4 mm and 16 mm, or
   2. 2) circular hollow sections with a thickness between 4 mm and 50 mm;
6. f) having as stress range the range of “hot-spot” stress;
7. g) having identical brace (branch) members.
