Precast Deck Beam Lifting Loops

Lifting loops for bridge decks typically consist of one or more 7-wire prestressing strands that have been bent into loops. Current national codes and handbooks do not provide guidance for the design of lifting loops for shallow members and consequently individual states and producers are using a variety of different methods. This has led to problems in the field including failure of loops and this poses a significant safety hazard. To address this concern, current practices are being reviewed and a range of lifting loop arrangements are being tested in order to develop a standard practice for the Illinois Department of Transportation (IDOT) with potential national application.
