TRB will conduct a webinar on Monday, September 17, 2018 from 1:00 PM to 2:30 PM ET that will present design equations for predicting the maximum lateral deformation and settlement of geosynthetic reinforced soil (GRS) under various configurations and service loads. This webinar will examine both bridge abutments and reinforced soil foundation for pier support. Presenters will describe the development of the equations, their validation using case histories, and their applications to bridge design. They will also showcase a graphical user interface that was developed based on the proposed equations.

This webinar was organized by the TRB Standing Committees on Transportation Earthworks and Geosynthetics.

Some registrants will need to pay $95 to attend this webinarSign into to view registration information.

Webinar Presenters

  • Ming Xiao, Pennsylvania State University
  • Tong Qiu, Pennsylvania State University
  • Mahsa Khosrojerdi, Pennsylvania State University

Moderated by:  Jennifer Nicks, U.S. Department of Transportation

Webinar Outline

  1. Introduction to design tools
  2. Development and validation of design equations
  3. Design tools and graphical user interface
  4. Question and answer session

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.

Learning Objectives

At the end of this webinar, participants will be able to:

  • Apply design tools to deformation analysis of GRS bridge support systems
  • Evaluate service limit state performance of bridge supports

 Professional Development Hour Information

A certificate for 1.5 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups, only the person that registers and attends the session will receive a PDH certificate. Certificates of Completion will be issued only to individuals who register for and attend the entire webinar session.

Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through as verification of your attendance to the Florida Board of Professional Engineers.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

This webinar was developed in March 2018. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005.
