SIMULATED SEISMIC LOAD TESTS ON REINFORCED CONCRETE COLUMNS

This paper provides results of seismic-load tests conducted on 11 reinforced concrete columns with low, moderate, or high axial compressive loads and reversible quasi-state lateral loads to simulate severe earthquake loading. The tests were conducted to check an analytical approach for the determination of the available flexural ductility and the enhancement of flexural strength of columns with various levels of transverse confining reinforcement. Comparisons of the experimental results and the theoretical predictions indicate that the cyclic moment-curvature theory and the derived design charts for ductility give sufficiently accurate and yet conservative predictions. Also, design charts for ductility give a more satisfactory prediction of the behavior of columns, which supported the basis of the derivation of the refined design equations for the quantities of confining reinforcement required in the potential plastic-hinge regions of columns.
