Abstract:
When designing concrete structures, fatigue related problems are not among the first that come to mind. However, structures subjected to strong cyclic loads such as those associated with destructive earthquakes experience strength and stiffness degradation that are most aptly described as a low-cycle fatigue phenomenon and are related to the damage accumulated under such loading. This paper briefly discusses the various elements of a rational, i.e. mechanics-based design methodology. Results of an experimental test program are summarized, in which 4-inch cubes with or without fiber reinforcement are subjected to uni- and biaxial cyclic compression until failure. The review concludes with a brief review of the various aspects of material behavior that need to be modeled, if the response of reinforced concrete members is to be simulated numerically.
