GFRP Shells with Transverse CFRP Strips to Retrofit Deteriorated Timber Piles - CICI Core Project

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

Start Date: 7/01/19

End Date: 6/30/20

Abstract

This project investigates the performance of prefabricated GFRP shells with CFRP strips to restore the lost strength of deteriorated load-bearing timber piles. Specimens of the shell system will be tested in pure hope tension using the environmental chamber to optimize the elements making up the shell. Subsequently, a series of small-scale axial compression tests will be designed and tested applied to short timber piles with representative levels of damage induced. Finally, a series of large-scale flexural tests will be designed and tested applied to long timber piles. The timber elements and the GFRP shell systems will be provided by IAB member Warstone according to the specifications requested. Design recommendations will be provided allowing the GFRP shell system to be applied to deteriorated timber piles efficiently and effectively.

End Date: 6/30/20

Abstract

A project focused on the strengthening of reinforced concrete columns under reverse cyclic loading is proposed. Concrete columns will be produced with integrated foundations and will be strengthened with various types of Fiber Reinforced Polymer strengthening systems. The strengthening will be focused on flexural strengthening through confinement and on shear strengthening through external FRP stirrups. All columns will be loaded under reverse cyclic load histories in the presence of axial load. The goal of the program will be to investigate whether various systems can meet building code requirements for FRP strengthening systems.

Evaluating Integral Abutment Performance

Sponsor: NC Department of Transportation

Start Date: 8/01/19

End Date: 7/31/21

Abstract

Integral abutment (IA) bridges may provide many advantages over conventional bridges during construction and subsequent maintenance. NCDOT has been designing various types of IA bridges. Unlike conventional bridges, IA bridges do not have expansion joints within the bridge deck or between the bridge deck and supporting abutments. Expansion joints and bearings in a conventional bridge are costly, and leaking joints cause deterioration of girders and bearings — leading to potential¬ly unsafe conditions and high maintenance and repair costs. Besides cost savings related to construction and maintenance, IA bridges also provide superior performance during extreme loading events, such as earthquake and blast loading, and are being built at an increasing rate in the United States. NCDOT began utilizing integral abutments in 2006. Since that time, NCDOT has provided varying guidance and details for integral abutments, but the overall performance of each detail has not been documented. Because IA bridges are built without expansion joints, thermal expansion and contraction must be accommodated by movement of the abutments. Thus, significant forces can develop in the bridge structure, abutments, piles, and soil surrounding the bridge substructure. The magnitude of these forces and response of the IA bridge to them is strongly dependent on the stiffness of the bridge structure, pile foundations, and soil. If the piles and soil are too stiff, large unwanted forces/stresses may develop in the bridge. On the other hand, if the backfill is relatively flexible and the embankment and foundation soil is stiff, unwanted yielding of the piles may occur at the bottom of the abutment. The fact that the soil response is strongly dependent on moisture content, which can vary significantly both seasonally and over the life of the bridge, results in unexpected problems. NCDOT reported that components of their integral abutments have been removed, added, or revised to address construction and maintenance problems without monitoring the influence of the revisions. Evaluation of these revisions is needed and recommendations for updates provided, as required.

Abstract

Abstract: The NSF IUCRC for Integration of Composites into Infrastructure (CICI) is specialized at innovating advanced fiber-reinforced polymer (FRP) composites and techniques for the rapid repair, strengthening or replacement of highway, railway, waterway, bridge, building, pipeline and other critical civil infrastructure. The Center consists of West Virginia University (WVU) as the lead institution in the current Phase II, with North Carolina State University (NCSU), the University of Miami (UM), and the University of Texas at Arlington (UTA) as partner university sites. CICI is currently establishing an international site at the Center for Engineering and Industrial Development (CIDESI) in Queretaro, Mexico, through a collaboration between NSF and the National Council of Science and Technology (CONACYT) in Mexico. The primary objective of the Center is to accelerate the adoption of polymer composites and innovative construction materials into infrastructure through joint research programs between the university sites in collaboration with the composites and construction industries. In Phase III, CICI aims to broaden its scope of research in composites to include: 1) nondestructive testing methods; 2) manufacturing techniques, such as 3D printing; 3) inspection techniques, such as the use of drones with high resolution cameras; 4) in-situ modifications of infrastructure systems, resulting in enhanced durability and thermo-mechanical properties; and 5) cost-effective recycling of high value composites, enabled by the addition of CIDESI.

Rapid Seismic Repair of Column to Footing Connections – Phase 2

End Date: 5/31/22

Abstract

Bridge column repair has been studied for some time with several established techniques for repair for shear and confinement critical columns. Recent research at NC State has demonstrated the feasibility of repair of heavily damaged bridge columns, including those suffering buckling and fracture of reinforcement, through the use of ‘Plastic Hinge Relocation’. That research led to the development of a set of repair techniques using both conventional and advanced materials. The research described in this proposal aims to further advance the techniques that have been developed, while identifying others that may lead to a more efficient repair design. The specific objectives of the research described in this proposal are to: (1) Experimentally verify the behavioral mechanisms developed in the prior study; (2) Investigate options for simplifying the repair process through alternative connections between adjoining members; (3) Evaluate alternative forming options for the repair region; (4) Study the use of rebar couplers for fractured bars; and (5) Evaluate residual drift limits within the context of complete bridge structures. The above will be accomplished through large scale tests that will take advantage of columns already constructed and tests as part of a different research program. In addition, the residual drift computational study developed in Phase 1 will be further developed to evaluate its performance for more complex bridge systems. Recommendations will consist of additional repair technique alternatives that can be implemented into the design guide developed during Phase 1. It is worth noting also that although the focus of this project is on earthquake induced damage, the repair techniques developed will also be applicable to the repair of other forms of damage, including environmental deterioration such as steel reinforcement corrosion and ice flows.

Start Date: 7/01/17

End Date: 5/15/20

Abstract

In seismic regions it is often necessary to strengthen the cold joint of a concrete wall-to-slab interface and to provide load-path continuity for the longitudinal interfacial shear developed from in-plane loading. Engineers are designing and implementing such details without any direction from existing design guides. The purpose of this project is to experimentally test a common design detail used in practice to observe its full behavior to failure and quantify the contribution of the FRP strengthening system to the total shear resistance. It is common for these details to specify FRP spike anchors to prevent, or delay, debonding of the FRP strengthening system. Hence, there is also a need to quantify the behavior of FRP spike anchors in small-scale single-shear test specimens since design guides and anchor manufacturers provide very limited useful information on their design and capacity.
