Steel Structure Trivia: Buckling Restrained Braces

A full-sized mockup frame of AISC Member Star Seismic’s buckling restrained braces (BRB) is currently on display at the “Designing for Disaster” Exhibit located in the National Building Museum in Washington, D.C. BRBs harness the ductility of steel to provide sustained protection against both seismic and wind loads and deliver superior seismic performance through a yielding core with an engineered separation from the surrounding concrete and steel casing.

Trivia Question: What decade was buckling restrained brace frame technology introduced?

A. 1960s
B. 1970s
C. 1980s
D. 1990s


The correct answer is “D. 1990s.” Congratulations to our winners: Blake Kaplan, city editor at The Sun Herald newspaper, Biloxi, Miss; Carolina Slaiman Molina, a civil engineering student at the Instituto Tecnologico de Santo Domingo, Dominican Republic; and John Suprien, also a student at the Instituto Tecnologico de Santo Domingo, Dominican Republic.

The Designing for Disaster Exhibit examines how risk from natural hazards such as wind, water, fire, and earthquakes is assessed and how policies, plans, and designs yielding safer, more disaster-resilient communities can be developed to better preserve the health, safety, and well-being of the public.

The exhibit focuses on disaster mitigation as an evolving science and highlights the tools and strategies that today's planners, engineers, designers, scientists, environmentalists and various community leaders are adopting to build safer and more robust infrastructure.

Along with Star Seismic’s BRB display, other engineering solutions featured at the exhibit include a partially deconstructed FEMA-specified safe room that can withstand wind speeds over 250 mph, a continuous load path that creates a chain within a home that holds it together if buffeted by hurricane-force winds, and a replica of Florida International University’s “wind wall,” which can generate category 5 hurricane winds.

The exhibit runs until August 2, 2015. For more information, visit

And you can test your steel structure knowledge right here on our MSC website on the last Friday of each month, where a new trivia question will be posted to the Steel in the News section. Our next question will be posted on Friday, October 31, at noon (CT).

The first three people to submit the correct answer will receive an MSC-branded, stainless steel back scratcher! (And check out that telescoping action! Wow!) Its five-fingered curved design reaches from 5 1/2 in. to 19 1/4 in. in length.
