With the development of accelerated bridge construction (ABC), the seismic performance of typical ABC column-footing connections has been evaluated in high earthquake-prone states, like Utah, California, Nevada, and Idaho. But to date, the current literature has yet to fully examine the impact behavior...

With the popularization of accelerated bridge construction (ABC), the utilization of splice sleeve connections has been researched to determine their performance using a variety of connection details and under several loading scenarios. However, fundamental research on the load distribution and load...

In several states, bridge deck delamination of reinforced concrete bridge decks built with partial depth precast concrete panels and cast-in-place concrete has been observed. The partial depth precast concrete panels are typically prestressed. Recently, one such failure was observed in Utah. There is...

A new method for building seismically resilient bridges is proposed using accelerated bridge construction (ABC) methods. The hybrid two-column bridge bent consists of post-tensioned precast concrete columns with a buckling restrained brace (BRB) as an external energy dissipation device. The design of...

The use of precast concrete in bridge construction has been abundant in recent years because of its efficiency and superior quality control. Precast components are connected at the bridge site to reduce construction time and traffic disturbance. The Grouted Splice Sleeve (GSS) connection provides good...

A mechanical bar splice, also known as bar coupler, is an alternative to the traditional lap splicing to connect bars in reinforced concrete (RC) structures. Even though mechanical bar splices can be used as new precast column connections to accelerate bridge construction (ABC), the use of bar couplers...

Precast concrete construction has been proven to be very efficient in bridge engineering, especially in accelerated bridge construction (ABC), where precast concrete components are connected to save time and minimize disruption of traffic. Post-tensioned (PT) concrete structural elements, when combined...

A study was conducted to develop recommendations for short span concrete structure type selection based on analyses of existing structure costs and performance data from South Dakota roadway systems. Through a combination of data sources, including the PONTIS database, local owner and inspector surveys...

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...
