  • Examining The Potential Of Thermoplastic FRP Tapes inside Highly Exothermic Overlays As A New Material For Rapid Bridge Deck Protection[IBT-ABC-UTC-2024-C2-OU01]: Some scenarios for concrete bridge deck repair involve inadequate bond between overlay and bridge deck leading to various distresses, including slippage, delamination, longitudinal joints failure, fatigue cracking, and rutting.  Inadequate bond does not allow the cross-section act as a single monolithic unit (Figure 3). This is detrimental to structural integrity and causes major problems associated with bridge deck failures. Detecting and repairing this damage is often costly and time-consuming due to the inaccessibility of the underlying concrete for direct inspection. To maintain durability over its design life, special attention should be given to the protection of bridge decks to prevent serious damage to the concrete and structural reinforcement.
  • Estimating Environmental load Demands Considering Weather Extremes To Enhance Resiliency Of Oklahoma Bridges [IBT-ABC-UTC-2024-C2-OU02]:Bridges are critical components of transportation infrastructure facilitating uninterrupted flow of goods and services within communities. However, the growing frequency and intensity of natural hazards and extreme weather events are escalating the vulnerabilities of bridge infrastructure. In recent years, Oklahoma has faced an increasing frequency of extreme weather events, including tornadoes, rising temperatures, and flash floods.

1st-Cycle Projects (2024-grant)

  • Prestress Losses in UHPC and Hybrid Precast, Prestressed Bridge Girders [IBT-ABC-UTC-2024-C1-OU01] : There are three objectives of the proposed research. The first objective is to measure prestress losses for full UHPC prestressed bridge girders. The second objective is to evaluate the effect of a hybrid UHPC-conventional concrete girder design on prestress loss behavior. The third objective is to evaluate the effectiveness of different design details for mitigating stresses in the girder end region and their effect on hybrid girder capacity.
  • Role of Grout and GFRP Slip Liner on the Circumferential Behaviour of Retrofitted Corroded Metal Culverts [IBT-ABC-UTC-2024-C1-OU02] :The project will focus on evaluation of a retrofitted system in a field dominated behavior. Information on three main aspects of behavior will be provided by the activities in this project: (a) circumferential behavior of retrofitted CMPs with combination of GFRP slip liner and different grout systems, (b) isolated behavior of the bonding material from the slip liner behavior and composite system behavior after retrofit, and (c) stiffness factor and load capacity design parameters to retrofit CMPs with GFRP slip liner using different grouts.
