Evaluating Louisiana New Deck Continuity Detail for Precast Prestressed Concrete Girder Bridges

The main objective of the proposed research is to evaluate the field performance of a continuity detail that will be included in the new Louisiana BDEM. The new detail is different from the standard continuity detail in the current Bridge Design Manual. It will be employed in a new bridge in Catahoula parish. The research plan will achieve the following goals: developing a comprehensive monitoring system that is capable of capturing the key behavioral parameters needed to evaluate the LS detail and to assist in the procurement and overview of the installation of the monitoring system; collecting data from an installed monitoring system over an extended period starting as early as pouring day until end of project period. Collected data will be analyzed and interpreted to understand the behavior and performance of the LS detail; and developing a user friendly monitoring software tool to assist in managing big data expected from long-term monitoring. The software tool will be developed with a Graphical User Interface (GUI) to assist users in manipulating, viewing, post-processing, and analyzing data using sophisticated scripts in a transparent way to the user. In addition, the ultimate goal of the project is to provide the Louisiana Department of Transportation and Development (LADOTD) with useful information on the performance of the LS detail, to assist in validating the simplified design procedure currently used to determine link slab reinforcement. Such information will help improve the LS detail and permit the comparison of its performance with other continuity details.
