REINFORCED CONCRETE CONNECTION HYSTERESIS LOOPS

Twenty-two reinforced concrete beam-column T-shaped connections were constructed using the same strength of material and geometrical configuration for each specimen. Test loading conditions were chosen to represent earthquake loading producing steel strains well beyond yield. The three test parameters examined in detail included magnitude of column axial load including axial tension, the magnitude of hinge rotation, and the number of cycles of inelastic loading. Test results show that these exterior connections were able to sustain a large number of inelastic cycles and still function, and that the most rapid change in hysteretic behavior occurred during the first cycle. The effect of column axial loading is that tension causes more rapid changes in the hysteretic behavior than compression.
