Cyclically loaded structures

WebAug 24, 2024 · In cyclically loaded structures, structures subjected to fatigue or some members in a seismic force-resisting system, backing can’t be left in place. Investigations of events (such as the Northridge earthquake) show backing left in place creates stress risers that contribute to cracking and connection failures. WebMay 25, 2007 · This section considers cylclic loads as either fluctuation of stress from load application and removal (one way stress) or loading to stress and reversal of loads (load reversal). Section 5.10.4 requires the removal of backing for cyclic loading, which as defined above would seem to include one way stress. Anybody disagree? Bob Garner
