REINFORCED-CONCRETE FRAMES SUBJECTED TO CYCLIC LOAD
Pages 32

SUMMARY This chapter summarizes important facts known about the response of reinforced concrete frames to cyclic loads. Since the most severe of such loads result from destructive earthquakes, much information on the behavior characteristics, analysis techniques, and design considerations, is drawn from the earthquake-engineering literature. The response of concrete frames to severe cyclic load is accompanied by a gradual process of strength and stiffness degradation, which can be considered a low-cycle fatigue phenomenon. Recent advances in the fields of modeling and analyzing concrete frames for such loading are reviewed.
