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...

A numerical model simulating the seismic behavior of precast concrete columns confined with glass fiber reinforced polymer (GFRP) spirals and longitudinally reinforced with steel or a combination of steel and GFRP bars was developed using the Open System for Earthquake Engineering Simulation (OpenSees)....

Fiber reinforced polymer (FRP) composite materials have been studied and applied to reinforced concrete (RC) structures for strengthening or seismic retrofit for many years. This research is related to using FRP composites in new bridge structures. Capacity degradation in RC components of existing bridges...

According to the 2017 ASCE Infrastructure Report Card (ASCE 2017), 9.1% of the U.S. bridges are structurally deficient. The majority of deficient bridges are in service on low-traffic volume roads, and these bridges should be replaced or repaired for public safety in a timely manner. As an alternative...

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...

Local governments have an immediate need for low life-cycle cost bridge replacement alternatives. Knowledge of available alternatives and construction planning processes hold potential for South Dakota local governments to replace more structurally deficient local bridges with limited funds. Through...

This study evaluates the seismic performance of circular concrete-filled tube (CCFT) columns in accelerated bridge construction (ABC) projects. CCFT components are considered of interest for bridges subjected to seismic forces due to their efficient structural behavior under combined axial and bending...
