• Abstract:
  The goal of everyone in the transportation community is to build bridges ; that are economic, easy to construct, and durable. Therefore, accelerating ; bridge construction through the use of precast concrete or prefabricated ; steel girders is a common practice for the majority of bridge projects. If ; left unconnected, each span will become simply-supported, which forfeits ; the structural advantages that continuous structures off er (i.e., smaller ; straining actions). Furthermore, joints between adjacent spans lead to ; a host of issues such as increased maintenance costs over the life of the ; project, deterioration of structural elements in the joint’s vicinity due to ; water leakage through the joint, and reduced riding quality. Therefore, ; developing details to connect adjacent spans has been an active area of ; research for a long time.
