3Appendix 3 Fatigue

This appendix applies to members and connections subjected to high-cycle loading within the elastic range of stresses of frequency and magnitude sufficient to initiate cracking and progressive failure.

User Note: See AISC Seismic Provisions for Structural Steel Buildings for structures subjected to seismic loads.

The appendix is organized as follows:

3.1. General Provisions 3.2. Calculation of Maximum Stresses and Stress Ranges 3.3. Plain Material and Welded Joints 3.4. Bolts and Threaded Parts 3.5. Fabrication and Erection Requirements for Fatigue
