Interim Conclusions, Recommendations, and Design Guidelines for Durability of Post-Tension Bridge Substructures
The use of post-tensioning in bridges can provide durability and structural benefits to the system while expediting the construction process. When post-tensioning is combined with precast elements, traffic interference can be greatly reduced through rapid construction. Corrosion protection of the post-tensioning system is vital to the integrity of the structure because loss of post-tensioning can result in catastrophic failure. The research program invovles exposure testing of twenty-seven large-scale beam specimens and ten large-scale column specimens to investigate numerous combinations of variables for durable post-tensioned substructure design. Beam variables include prestress level, loading, grout type, duct splices, concrete type, strand type, duct type, and end anchorage protection. Column variables include foundation connection, post-tensioning protection, concrete type, and loading.
