Rapid Construction of Bridge Bents with Precast Concrete

Bridge construction can dramatically increase traffic delays and congestion, particularly in urban areas with heavy traffic volumes. Traffic disruption could be reduced significantly if reinforced concrete columns and cross-beams could be precast offsite, and then rapidly assembled together at the bridge site. Such systems have been used successfully to construct bridges in states with low seismic activity (e.g., Texas), but the systems used in those states are not suitable for the level of seismicity in Western Washington State. To take advantage of the benefits of using precast components in bridges in Washington State, it is necessary to develop precast concrete systems that can be constructed quickly and that have good seismic performance. The objective of the proposed second phase of the research is to develop connection details and design procedures for several bridge bent systems, and to confirm by physical testing the structural performance of the three most promising ones, both under (non-seismic) erection loads with partially completed connections and under simulated seismic loading after the connections are complete.
