Seismic Performance of SCC Bridge Columns

Self-consolidating concrete (SCC) is a specially proportioned hydraulic cement concrete that enables the fresh concrete to flow without segregation. Because of its high workability, SCC flows into narrow spaces and form corners, and around closely-spaced steel reinforcement without the need for mechanical vibration. In seismic regions such as Utah and part of Colorado in Transportation Region 8, the need for a large amount of confinement reinforcement to provide the required ductility often results in columns and joint regions with excessive steel congestion. Steel congestion hinders the placement and proper consolidation of conventional concrete. There are also cases when concrete repair and/or replacement are needed to fix localized damage in bridge structural elements following a seismic event. Highly flowable, yet non-segregating, concrete would be needed to perform the repairs. The high flowability and robustness of SCC make it ideal for the construction and repair of bridge columns and joints designed to meet seismic detailing. There is an evident lack of research to investigate the ductility and shear strength of SCC bridge columns and joints under seismic loads. In this proposed study, experimental and analytical work will be performed to evaluate the ductility and shear strength of columns and joints under reversed inelastic deformations. The objectives of this research projects are: (1) Develop a stress-strain model for SCC under uniaxial compressive stress; (2) Evaluate the ductility and shear capacity of SCC bridge columns under inelastic load reversal; and (3) Evaluate the ductility and shear capacity of SCC bridge columns-beam joints under inelastic load reversal.
