WHAT HAS BEEN LEARNED FROM THE FIRST PRESTRESSED CONCRETE BRIDGES--REPAIR OF SUCH BRIDGES

Engineers often wonder to what extent prototype structures have lived up to their expectations. As examples, old construction of the Walnut Lane Bridge, Amdeck section, and one other structure which showed signs of distress over the years will be illustrated. The speaker will discuss the apparent background and reasons for such a distress plus the improvements which may be made to make such effects less severe. Also, methods of repair and what has been learned from these old designs will be described. The lecture is supported with many color slides and viewgraphs which depict old construction details and the increasing severity of distress. Accidental damages caused by vehicles on three different types of prestressed bridge superstructures are also illustrated. /Author/
