Even though mechanical bar splices can be used as new precast column connections to accelerate bridge construction (ABC), the use of bar couplers... Precast prestressed double-tee girders are common on county bridges in South Dakota because of the ease of construction, short construction time, and low cost. However, the longitudinal joints of these bridges are rapidly deteriorating, imposing girder replacement after only 45 years of service. Currently... The most common type of bridge on South Dakota local roads is a precast prestressed double-tee (DT) girder bridge. More than 700 DT bridges are currently in-service in South Dakota. Structural detailing, aging, traffic volume, and environmental conditions affect structural performance, integrity, and... The South Dakota Department of Transportation (SDDOT) allows the use of precast double-tee bridges in counties because they are economical and fast in construction. Alternative durable prefabricated bridge systems are needed to provide more options to local governments. The present study was carried... Compared with conventional lap splicing, mechanical splicing is an alternative method of connecting bars in reinforced concrete (RC) structures, and is used mainly to reduce bar congestion in joints. Recently, mechanical bar splices, which are also referred to as bar couplers, have been used in laboratories... |
