TRB will conduct a webinar on Tuesday, April 24, 2018 from 1:00 PM to 2:30 PM ET that features research from the National Cooperative Highway Research Program (NCHRP)’s Research Report 851: Proposed AASHTO LRFD Bridge Design Specifications for Light Rail Transit Loads.

This webinar will describe the behavior of light rail transit bridges, live loads and their associated forces, rail-train-structure interaction, and load factor calibration to implement the Load and Resistance Factor Design (LRFD) method. The presenter will explain how to design light rail bridges that adheres to the American Association of State Highway and Transportation Officials (AASHTO) Guide Specifications for Light Rail Bridges.

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

Webinar Presenter

  • Jimmy Kim, University of Colorado at Denver

Moderated by:  Bill DuVall, Georgia Department of Transportation

Webinar Outline

  1. Overview of NCHRP
  2. Transit load characteristics
  3. Load factors and combinations for bridges carrying light rail transit
  4. Analysis requirements for bridges carrying light rail transit
  5. Design requirements for bridges carrying light rail transit
  1. 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:

  • Discuss the current state of light rail bridge design
  • Describe the behavior of bridges subjected to light rail loadings along with various forces
  • Identify the effort to establish a new design approach for light rail loadings
  • Describe how to design light rail bridges pursuant to the AASHTO Guide Specifications for Light Rail Bridges

 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 October 2017. 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.
