Evaluation of the Effects of Superstructure Characteristics on the Performance of Bridge Decks under Traffic Loads

CAIT project no.: CAIT-UTC-REG78

Fiscal Year: 2021/2022

Status: In Progress

Principal investigator(s): Sharef Farrag, Ph.D. (PI), Rutgers, The State University
Nenad Gucunski, Ph.D. (Co-PI), Rutgers, The State University

Performing organization(s): Rutgers Cait

Managing organization: Rutgers CAIT

In cooperation with: Greenman-Pedersen, Inc.
Partner project manager: Richard Dunne, National Director Bridge Preservation

Supported by: USDOT-OST-R

UTC, grant, or agreement no.: 69A3551847102

Summary:

The primary goals of this proposal are to assess the stresses and displacements exhibited by the deck under traffic loads; conduct a parametric study encompassing multiple deck and superstructural material and geometric aspects, reflecting varying bridge superstructure systems, and evaluate the extent to which varying bridge superstructure and deck aspects contribute to the deterioration of the bridge deck.

The intended outcome of the project is to reveal which type of bridges are more prone to mechanical/vibration damage as opposed to those that exhibit electrochemical deterioration.
