RESEARCH GRANT: Improving the Safety of Rebar Cages using Innovative Connectors Phase 2: Failure Prevention of Below and Above Ground Rebar Cages (RGA #01-24)
The Charles Pankow Foundation (CPF) along with several Industry Partners is pleased to announce the award of a new research grant to the University of Nevada Reno (UNR) to continue investigation for improving safety while working with rebar cages. The Principal Investigator will be Hamed Ebrahimian, Ph.D., P.E., along with Ahmad M. Itani, Ph.D., S.E, of the Department of Civil and Environmental Engineering at UNR.
The objective of Phase II is to understand the failure mechanism of rebar cages and provide practical analysis, design, and detailing guidelines to prevent failure of below-grade rebar cages reinforced with mechanical connectors and/or internal stiffening elements, as well as above-grade cages that may be braced externally. Phase II aims to leverage the knowledge gained in Phase I and understand the failure mechanism of rebar cages under lateral loading conditions such as uneven tightening of guy wires (wire ropes), environmental loads, or accidental loads. These conditions are, for example, common during the installation of above-grade rebar cages. The objective is to provide practical analysis, design, and detailing guidelines to prevent failure of rebar cages throughout all stages of construction.
