Service Life Design Guidance for UHPC Link Slabs [ABC-UTC-2016-C3-OU01]: This project will examine service life design considerations for UHPC link slabs including economic analysis relative to other construction alternatives. The main objective of this project is to synthesize available information on UHPC link slabs to be used within the framework of SHRP2 R19A for service life design of bridges.
Development of Non-Proprietary UHPC Mix[ABC-UTC-2016-C2-OU01]: The primary objective of the project is to develop guidance for an “ABC-UTC Non-Proprietary UHPC Mix” design produced with local materials that can achieve the necessary mechanical properties and durability for use in bridge component connections. The five ABC-UTC partner institutions will coordinate efforts to examine material properties, reinforcing bar development length, shear behavior, full-scale joint behavior, and durability of the “ABC-UTC Non-Proprietary UHPC Mix.”
Performance of Existing ABC Projects: Inspection Case Studies[ABC-UTC-2016-C2-OU03]: This project has two components. The first component involves performance evaluation of two existing ABC projects. These projects will be selected in cooperation with the Oklahoma Department of Transportation and the ABC-UTC leadership at the Florida International University. The second component involves outreach (summer camp as an element) and center operation.
1st-Cycle Projects (2016-grant)
Development of Guide for Selection of Substructure for ABC Projects[ABC-UTC-2016-C1-OU01]: The primary objective of this project is to provide guidelines for decision making by the designers and bridge owners for the selection of substructure and foundation for new bridges and replacement of existing bridges using ABC methods. This is a joint project between FIU and OU, with OU focusing on foundation and FIU on remaining.
2nd-Cycle Projects (2016-grant)
Development of ABC Course Module – The Risk Due to Induced Earthquakes and Accelerated Solutions[ABC-UTC-2016-C2-OU02]: The objective of this continuing education course is to provide the bridge community with the opportunity to learn how to estimate the cumulative seismic demand on bridges, both accelerated and conventional, due to a large number of small-to-moderate earthquakes and to educate engineers on the potential use of ABC repair/retrofit technologies. The 1-hour web-based course will provide training on the ABC-UTC Guidelines for Assessing Effect of Frequent, Low-Level Seismic Events. Also, a brief survey of available ABC repair techniques appropriate for cumulatively damaged bridges will be provided.

Rapid Retrofitting Techniques For Induced Earthquakes – Phase I[ABC-UTC-2016-C1-OU02]: The objective of this project is to develop analysis techniques to study the effect of large number of small earthquakes on bridges and identify appropriate ABC methods for repair of bridges damaged by induced earthquakes. Expected outcomes will be new analysis tools and guidelines to assess for damage from induced earthquakes in Phase I (completed) and specifications for application of ABC repair methods in Phase II (unfunded).
