Lateral Bracing of Flexural Members

View Important System Requirements for viewing this course.

INSTRUCTOR: Alexander Newman, P.E., F.ASCE 

Course Length: 1.5 Hours

Sponsored by ASCE's Structural Engineering Institute and ASCE Continuing Education.  

The webinar allows the audience to see this seminar straight from my office, without having to travel. I have attended many ASCE webinars and find that ASCE knows how to put together an effective webinar.

Purpose and Background

Most structural engineers know that flexural members may need some lateral bracing to optimize their load-carrying capacities. But what kind of bracing? For which loads is the bracing designed? Which design details should be used? These questions are only the beginning.

There are many more detailed questions that come up during real-life design projects. For instance: Can a structural steel girder be laterally braced by the corrugated metal deck with the flutes parallel to its span? Do joist hangers provide rotational support at the ends of wood rafters? How often should the antiroll braces be placed at the supports of Z purlins used in pre-engineered buildings? Should an isolated concrete beam be laterally braced? When is cross-bridging needed for wood floor joists?

This webinar discusses these and many other practical issues involved in designing and specifying lateral bracing for flexural members of various materials. The presentation starts with the basics of bracing design applicable to all types of beams and joists. It then proceeds to an in-depth examination of the bracing practices for flexural members in wood, concrete, structural steel, and pre-engineered metal buildings.

Borrowing from more than 30 years of engineering and forensic experience, the instructor explains which designs worked better than others and which common details could be improved. The design examples and sketches of various bracing systems illustrate the discussion.

Learning Outcomes

  • Learn about the general types of bracing used in flexural members
