Dr. Majid Talebi, P.E., will be presenting his thesis study, Analysis of the Field Behavior of a Geosynthetic Reinforced Soil Integrated Bridge System during Construction and Operation, at the Engineering Center located at 4359 Lindell Blvd. in St. Louis on Friday March 9th. Registration is from 11:00 – 11:30 am, with lunch from 11:30 am – 12:00 pm, and the program from 12:00 – 1:00 pm. The cost is $25 for Engineers Club and Affiliate Society Members, $40 for non-members. Reservation limited to 100 people, 1 PDH to be provided. Abstract for the presentation is below:
The Geosynthetic Reinforced Soil Integrated Bridge System (GRS-IBS) is a composite bridge structure built using GRS abutments and prefabricated bridge superstructure elements. This accelerated bridge construction technology has been developed and promoted by researchers and engineers from the United States of America’s Federal Highway Administration (FHWA). GRS-IBS technology has proven itself useful for rapid, cost-effective bridge construction in other regions of the United States. Consequently, the Delaware Department of Transportation (DelDOT) constructed the first GRS-IBS in the state of Delaware (Br. 1-366) in 2013 to explore the effectiveness of this technology for use within their own bridge inventory.
This presentation provides an overview of the design, construction, and monitoring process that was utilized to deploy the first constructed GRS-IBS in Delaware. Recorded performance data for the structure from the time of construction, live load testing, and over two years of in-service operation were collected using different types of instruments and analyzed. The corresponding details are presented in this presentation.
