HSS Articles

HSS Bollards

Bollards are utilized inside structures to prevent accidental impact from forklifts or other vehicles. They are also used outside structures to prevent vehicles from accessing restricted areas. The most common bollard is a simple, concrete filled HSS designed to resist flexure. Read this article by Dr. Jeffrey Packer to explore design considerations and see a design example for concrete filled HSS bollards.

Nurturing the Next Generation of Engineers and Exploring New HSS Connections for the Future

Dr. Jason McCormick is a professor in the department of civil and environmental engineering at the University of Michigan. Hear his insights on mentoring aspiring structural engineers, designing with HSS bollards and more in this edition of STI Peer Perspectives.
