in Bridgeport, Ohio (ODOT Dist. 11), the BEL-7-1975 bridge carries north- and south-bound
SR7 over I-70 and various existing features. The twenty-two-span structure has
a total length of over 1600 feet. Many of the pier caps have seriously deteriorated
and required repairs after 50 years of service. This presentation will summarize
and explain how to strengthen the deteriorated T-type pier caps using external
post-tensioned bars. This unique temporary repair method, although straightforward
in design and construction, has had limited use in Ohio.
