Introduction to the Shakedown Behavior of Steel-Framed Structures
Steel structures subjected to variable repeated loads may fail by high or low-cycle fatigue, or by incremental collapse. Shakedown occurs when, after several excursions into the inelastic range, a residual moment field develops and all subsequent load cycles are resisted by elastic behavior. The maximum load pattern at which shakedown just occurs is the incremental collapse load. This lecture presents background, theory and examples on the shakedown behavior of steel-framed structures.
This course is based on a past NASCC session.
