Abstract:
Response of reinforced concrete columns to seismic loading was investigated experimentally. Full-scale columns were tested under slowly applied lateral load reversals. Both unidirectional and bidirectional loadings were included. Columns with and without axial loads, including variable axial tension and compression, were tested. The test parameters included axial load, shear/confinement reinforcement, and deformation path. Test results indicate that axial loads have a significant influence on hysteretic response of columns. Column capacity changes with the concurrent level of axial load, axial compression reduces column response, and bidirectional load cycles can produce severe strength and stiffness degradation.
