A Charles Pankow Foundation investigation geared to identifying fabrication and assembly practices curtailing rebar cage collapse or failure incidents confirms the potential of U-bolt hardware to replace tie wires commonly used in lateral and transverse bar connections and increase lateral strength. The Haymarket, Va. organization teamed with the American Society of Civil Engineers Construction Institute, University of Nevada, Reno and…

CO2Concrete, an entity incubated at the University of California, Los Angeles, has changed its name to CarbonBuilt to better align with a mission to store significant amounts of carbon dioxide in concrete used for the built environment. Developed over the course of seven years at the UCLA Samueli School of Engineering-hosted Institute for Carbon Management, the CarbonBuilt Reversa platform spans…

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.

Sources: Charles Pankow Foundation, McLean, Va.; CP staff
A Charles Pankow Foundation grant will fund “Seismic Precast Concrete Wall and Frame Structures with Short-Grouted Ductile Rebar Connections,” a University of Notre Dame Department of Civil & Environmental Engineering and Earth Sciences investigation under Yahya Kurama, PhD, PE. Findings could support the development of commercially available connectors holding the potential to simplify precast wall and frame construction.

Sources: Charles Pankow Foundation, McLean, Va.; CP staff
The Charles Pankow Foundation’s latest grant will help fund a project, “Foundation Mats with High Strength Steel Reinforcement,” under principal investigator Jack Moehle, Ph.D., University of California, Berkeley. Project findings stand to further validate the case for elevated rebar strength thresholds in American Concrete Institute and model building code language. Joining the Pankow Foundation as research allies are the ACI Foundation and Concrete Reinforcing Steel Institute Education and Research Foundation.
