Innovative Multi-Hazard-Resistant Bridge Columns for ABC

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 also enhance work-zone safety. While several techniques are available to accelerate bridge superstructure construction, limited techniques are available to accelerate bridge substructure construction. Hollow-core FRP-concrete-steel (HC-FCS) columns – a concrete core sandwiched between an outer FRP tube and an inner steel tube – provide a potential solution for accelerating bridge substructure construction and offer the following advantages over traditional construction materials and systems: Enhanced ductility and energy absorption; Improved axial and flexural strength; Enhanced durability and corrosion resistance; Simplified construction techniques; Decreased overall column weight; Reduced material and labor costs; and Longer life. Because of their significantly enhanced ductility compared to existing bridge columns, HC-FCS columns also provide a column system better able to resist multiple hazards such as earthquakes, vehicular impact, blast, overload, excessive thermal stresses, progressive collapse, and fire. Previous research combined with the results of this proposed study and a companion Oklahoma Department of Transportation (ODOT) study will provide the necessary performance data and recommendations to move HC‑FCS columns into practice.
