Abstract:
The compressive strength of concrete at bearing areas is increased due to confinement of surrounding concrete and reinforcement. Design codes propose criteria for resistance when the load can distribute in two directions for static loading but not specifically for fatigue loading. This study focuses on concentrated load distributing in one direction with confinement in the transverse direction. Six concrete specimens subjected to static loading and six specimens subjected to fatigue loading in compression were tested. In conclusion, the observed loads were in good agreement with the standards for static loading. For fatigue loading, definite conclusions could not be drawn due to the limited number of specimens tested.
