Abstract: Infrastructure construction is increasingly moving toward the use of prefabricated elements and systems. However, this trend has exposed the challenge of effectively assembling an infrastructure unit (e.g., a bridge) such that the final product performs as well or better than a traditionally constructed unit. Ultra-high performance fiber-reinforced concrete (UHP-FRC) has emerged as a solution to this challenge, allowing for constructible, cost-effective connections whose performance emulates or exceeds traditional concrete construction. UHPFRC connections are particularly advantageous because of the short development lengths of embedded reinforcements, the high tensile and bond strengths, and the flowable rheology. Applied engineering research at the U.S. Federal Highway Administration and elsewhere has developed a series of connection concepts that are beginning to be deployed in bridges across the U.S., including panel-to-panel connections, panel-to-beam composite connections, and column-to-beam connections. The concepts, opportunities, and gaps are presented herein.
