Abstract:
Through a collaboration between the University of Nevada, Reno (UNR) and Con-Fab Precast Inc., several UHPC columns were fabricated using production scale techniques such as ready-mix trucks. Two different types of steel fibers were used: manufactured virgin steel fibers and recycled tires steel fibers and wires. The columns are connected to conventional concrete footings using different Accelerated Bridge Construction (ABC) seismic connections to be tested at one of UNR’s shake tables under combined axial and lateral earthquake loading. An overview of the construction experience and preliminary findings from the specimens assembly and testing at UNR are discussed in this presentation.
