Rebar connector research team targets large cage safety

Sources: Charles Pankow Foundation, McLean, Va.; CP staff

A lack of proper engineering design and detailing procedures to safeguard slurry wall foundation, cast-in-drilled hole pile and tall column rebar cage stability has compelled a Pankow Foundation grant for the American Society of Civil Engineers Construction Institute, teaming with the University of Nevada, Reno. Researchers will examine behavior of cages incorporating innovative mechanical connectors—U-bolt, threaded rod with plate and wire rope—during various loading conditions.
