Video: Basics of Limit States and LRFD Bridge Design

The SSSBA presents a topic based video series on short span steel bridges.

In this series, Dr. Gregory Michaelson (Co-Director, SSSBA Bridge Technology Center & Associate Professor, Department of Civil Engineering at Marshall University) will review basic concepts and ideas pertinent to engineers new to short spans steel bridge design and those looking for a refresher in fundamental concepts.

This video focuses on the basics of limit state and LRFD bridge design.

The goals of this video are:

• To introduce the basics of limit state design and how engineers design and detail bridges.
• To familiarize yourself with principles related to short span steel bridge design.

The outline of the video is as follows:

• Background (ASD vs. LRFD, Reliability)
• LRFD Limit States
• Relevant Resources
