2292 Innovative Multi-Hazard Resistant Bridge Columns for Accelerated Bridge Construction

The Federal Highway Administration (FHWA) and state departments of transportation (DOTs) are actively promoting accelerated bridge construction (ABC) to minimize construction costs and time and to enhance work-zone safety. While several techniques are available to accelerate bridge superstructures, limited techniques are available to accelerate bridge substructures. This proposal focuses on accelerating substructure construction using an innovative multi-hazard resistant bridge column. The column consists of a concrete core sandwiched between an outer fiber-reinforced polymer (FRP) tube and an inner steel tube. Both tubes will act as stay-in-place forms and confine the concrete core. The inner steel tube will be embedded into the footing and will provide flexural and shear reinforcement. The outer FRP tube will protect the concrete and steel materials from corrosion and will provide flexural and shear reinforcement. Both high-strength self-consolidating concrete (SCC) and ultra-high-performance concrete (UHPC) will be investigated for potential use as the concrete core material.
