Title: Axial Behavior of Reinforced Concrete Columns under Dynamic Loads
Author(s): Parviz Soroushian and Jungsung Sim
Publication: Journal Proceedings
Appears on pages(s): 1018-1025
Keywords: axial loads; columns (supports); compression; dynamic loads; mathematical models; reinforced concrete; stiffness; strains; strength; structural design; tests.
Abstract:Strain rate-sensitive constitutive models of steel and concrete were used for predicting the axial load-axial strain relationship of reinforced columns at different rates of straining. The analytical results were compared with results of tests on reinforced concrete columns. Effects of steel percentage and yield strength, confinement, moisture contents, and compressive strength of concrete, and cross-sectional shape on strain rate-sensitivity of column axial behavior were studied analytically. A practical design equation for computing column axial strength at different rates of straining was proposed.
