• Abstract:
  Post-tensioned concrete has been widely used for ; over 50 years. The first Sunshine Skyway Bridge, ; built in 1954, was one of the earliest structures in ; the U.S. to incorporate post-tensioned elements; ; its replacement also uses the technology. Post- ; tensioning has many advantages; for example, it ; allows longer, lighter spans. But this technique ; also has vulnerabilities, ; especially corrosion of cables ; or anchors, exacerbated by ; Florida’s hot, humid, often ; salty environment. Though ; failed tensioning components ; have never led to significant ; public safety concerns, ; the Florida Department ; of Transportation (FDOT), ; through its research program, ; continually seeks better ; methods of installation, ; inspection, and maintenance ; of post-tensioned structures.
