title = "Design and detailing of diaphragms in threaded rod continuity systems",
abstract = "Threaded Rod (TR) continuity system allows the girders to be continuous for deck weight in addition to live load. The bridge becomes continuous for approximately two-thirds of the total load which improves its load-carrying capacity, reduces deflections and deck cracking, and increases span-to-depth ratio. In this system, the precast prestressed concrete I-girders are connected at intermediate supports with high strength threaded rods above the top flange to resist the tension force and with concrete diaphragm to resist the compression force. This paper presents the TR continuity system and its advantages over conventional systems. In addition, this paper will propose the third generation TR continuity system and its advantages over previous TR continuity systems. The effects of bottom flange steel plates in comparison with confinement steel are presented in this paper. The required concrete strength of the diaphragms with proper detailing and reinforcement is investigated and presented in the paper as well.",
