Bio

Sami Rizkalla is distinguished professor emeritus of civil engineering and construction at North Carolina State University in Raleigh, North Carolina. He served as director of the Constructed Facilities Laboratory (CFL) and director of the NSF Industry/University Cooperative Research Center for the Integration of Composite into Infrastructure (CICI).

His research focused on the design, construction and performance of reinforced and prestressed concrete structures and bridges.

Education

Ph.D. Civil Engineering North Carolina State University 1976

M.S. Civil Engineering North Carolina State University 1974

B.S. Civil Engineering Alexandria University 1965

Area(s) of Expertise

Rizkalla's general research interest is the design, construction and behavior of reinforced and prestressed concrete structures and bridges. For more than 30 years, his research focused on the use of higher-performance concrete and fiber-reinforced polymer (FRP) materials for the construction, repair and strengthening of structures and bridges. His research interests also include diagnostics and prognostics of structures and bridges using nondestructive monitoring systems.

Funding Agencies: Center for Integration of Composites into Infrastructure (CICI) - NCSU Research Site

The primary purpose of the testing program would be to evaluate the ICC acceptance criteria currently in development for continuous or semi-continuous fiber-reinforced grid connectors anchored in concrete. In addition, data generated would be useful in characterizing the shear flow capacity of CGRID sandwich panel connections in various configurations.

Date: 07/01/14 - 12/31/15
Amount: $30,000.00
Funding Agencies: Precast/Prestressed Concrete Institute

The goal of the proposed research is to develop standard details for typical dapped end prestressed thin stemmed-members. The research scope includes extensive non-linear finite element analysis and full scale experimental. The investigation will examine existing test data, published literature, current design guides, advanced computer analyses, and experimental testing. Based on these results, the research will develop a comprehensive set of appropriate and practical design procedures and reinforcement details suitable for implementation.
