Utilization of Handheld Field Testing System for Improvement of Bridge Load Rating Values in Pontis

Due to the growing number of structurally deficient bridges in the United States, methods for determining the structural performance of in-service bridges is vital to the preservation of the nation’s bridge network. By utilizing field testing, the response of the bridge due to a known traffic load can be assessed, and more accurate structural performance can be determined. The objective of this research is to develop a field testing system that can be used assist the Pontis Bridge Management software in selecting suitable bridge candidates for repair or replacement. In conjunction with current development of a handheld device with Pontis inspection forms, development of a data collection system utilizing a handheld device that collects field test data to assist in the structural assessment of bridge structures will be completed. This will include the programming of the device, testing and verification of the system’s accuracy and usability, along with the methodology used to assess structural performance. A summary of how this system can improve the structural assessment of an in-service bridge will be included, along with how this system can be utilized to assist the Pontis Bridge Management System software in selecting bridge candidates for repair and replacement. The completed research outlines the use of a handheld data-acquisition system that can be used to improve the load rating of in-service bridges. Further development strategies are presented and their applicability to integration with the Pontis software.
