AISC and NSBA Announce 2024 Prize Bridge Awards
AISC and NSBA Announce 2024 Prize Bridge Awards

The American Institute of Steel Construction and the National Steel Bridge Alliance are recognizing eight bridges with 2024 Prize Bridge Awards—the structural steel industry’s highest design honor for bridges.

Albina bent 127,000# of tube steel for the South Bayfront Pedestrian Bridge and Horton Landing Park, Emeryville, California, a Merit Award Winner.

Albina induction bent 15 lengths of TS 16” X 16” X .625” WALL A1085 A513 to 149 ft and 289 ft radii and 9 lengths of TS 20” X 12” X .625” WALL A1085 A513 the easy way to 290 ft and 310 ft radii. Photo credit: Tom Loomis

How Much Stress Is Put on the Material When You Bend It?
How Much Stress Is Put on the Material When You Bend It?

Common questions we receive from customers have to do with the stresses put on materials during the rolling, curving, forming, and bending processes. 

  1. What stresses are put on the materials during the curving process?
  2. What is the stress, strain on the steel being bent or curved?
  3. Is the material weakened from the stress, strain during the curving process?
  4. Is there a stress, strain diagram for curved or bent steel?
  5. Is there a stress vs strain graph for curved or bent steel?

The easiest way to answer these questions is to reference the AISC Curved Member Design Guide #33.

https://www.albinaco.com/pdfs/design-guide-33.pdf

See Section 5.2 “Material Properties”

Cold bending involves inelastic straining of the member, which affects the material properties. These changes are primarily attributed to strain hardening and strain aging, which increases the yield stress, ultimate stress and hardness, and decreases the ductility and toughness. For curved members in buildings, the strains induced during the cold-bending process rarely exceed the potential strains induced in the manufacturing process of straight members.

The Awards just keep on coming! The National Steel Bridge Alliance has awarded the Williams Creek Shoup Bridge in Salem, Idaho a Merit Award in the Medium Span bridges category. Albina was happy to be a part of the project and provided 145,000# of bent structural steel and HSS including:

W18 X 234# A992
4 lengths x 100 ft- bent the easy way to a 179 ft radius
2 lengths x 75 ft- bent the easy way to a 179 ft radius

TS 8" X 8" X .375" WALL A500 GR B
8 lengths x 53 ft: bent to a 304 ft radius.

Albina Co., Inc. Recognized at "The Spheres" IDEAS2 Presidential Award  Ceremony
Albina Co., Inc. Recognized at "The Spheres" IDEAS2 Presidential Award Ceremony

"The Spheres" in Seattle, Washington have been all the buzz lately! "The Spheres" were featured in the May 2019 Edition of Modern Steel Magazine as the buildings were awarded the AISC's IDEAS2 Presidential Award for Excellence in Fabrication!  Just this last week, our VP of Sales, Brad Lund, was able to attend the award presentation ceremony at "The Spheres" in Seattle and we were awarded a plaque to display in our office. See below for some AMAZING pictures!


Albina Co., Inc. was the steel bender/roller for the Curved Steel Bio-Sphere buildings in Seattle, WA. Albina bent 750,000# and 1,050 pieces rectangular tube steel bent the easy way and a portion bent off-axis. Almost 8 miles of welding work and grinding was avoided because of Albina’s ability to bend a portion of the project. Almost NO correction was needed during fabrication or erection as the bends fit to the fixtures within 1/32nd of an inch! Albina Co., Inc. also bent the handrails and spiral staircase for the interior of the buildings.

Check out the August Issue of Modern Steel for “What’s Cool In Steel” Albina was the bender/roller on two of the featured projects including the Basher Pedestrian Bridge at the San Diego Zoo (pages 23-26) and a Des Moines sculpture titled “A Monumental Journey” by artist Kerry James Marshall (pages 30-31). We are working on securing some final install pictures of each of these projects! Stay tuned!

What's Cool In Steel

Exterior Images of Curved Steel at The Madison Center "Great Room" in Seattle, Washington

We were in Seattle this weekend and were able to get some exterior pictures of The Madison Center. The Madison Center is a 530 foot tall, 36 story high rise office building in Seattle, Washington and is featured in the June edition of Modern Steel. Albina Co., Inc. was the bender/roller on this project and worked specifically on what is being called "The Great Room" which is a 45-foot tall steel framed entryway rotunda. Albina bent many material types for this project including tube steel 8" x 6" up to 12" x 12", 3" x 3" angle, W10 and W16 wide flange, 8" pipe and more. Check out the article for some more details on the architectural feat and some great pictures. We will be heading back up to Seattle next week to get some interior shots. Stay tuned!

FREE DOWNLOAD of AISC's Design Guide 33: Curved Member Design AVAILABLE NOW!

AISC recently released the first ever Design Guide of its kind in the United States offering information on the fabrication, design and detailing of curved members and we are offering you a FREE DOWNLOAD of the Design Guide from AISC.

Design Guide 33 was a collaborative effort of the members of the AISC Bender/Roller committee. We worked together for many years to provide this invaluable resource for the industry. Modern Steel Construction recently published an article titled "Design with a Twist" in the October 2018 Issue giving a brief highlight of topics covered in the Design Guide. AISC also created a very insightful webinar for their continuing education program titled "Design of Curved Members." If you are interested in obtaining a print copy of the Design Guide to assist with your efforts in specifying curved steel members, please contact us and we will be happy to get one to you!
