Albina recently rolled 36 pieces of Tube Steel 6” X 6” X .375” WALL A500 GR C to AESS standards at radii ranging from 3’-9” – 24’-4” for the United States Air Force Academy Visitors Center. The visitors center is expected to open early 2024 and the 32,000 square-foot facility will include storytelling and high-tech exhibits reflecting the Air Force and Space Force missions as well as illustrating a day in the life of a cadet at the Academy.  The Visitors Center is viewed as more than a public entrance to the Academy, it is also a gateway to Colorado Springs. Six years in the making, the new area will also feature a hotel, retail space and office space. 

Below are a few videos with more details on the project.

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.

We have had the pleasure of providing many bent steel pieces for some fabulous projects at the San Diego Zoo including the Hummingbird Habitat, Komodo Kingdom, the Invert Building, the ZPA Catering Building, the Food Services Building, the Raintree Restroom and many more exhibits throughout both the Children’s zoo and the main part of the zoo.

Bridgeport Village, an upscale outdoor mall in Tigard, Oregon recently underwent a $35 million dollar modernization and now features covered seating areas, a central courtyard area with new landscaping, a performance stage, updated building facades and about 20 new storefronts. Albina Co., Inc. was instrumental in helping the developers update the storefronts and bent various materials including:

2 lengths x 40 ft: W10 X 22# A992
Albina to roll all possible from each length (the easy way) to a 40’-4” centerline radius.

4 pcs of 3” X 3” X ¼” ANGLE A36
Albina to roll all possible from each length (leg in) to a 42’-7” outside radius.

3 lengths x 20 ft: 3” X 2” X ¼” ANGLE A36
Albina to roll all possible from each length (3” Leg in) to a 59’-1” outside radius.

3 lengths x 20 ft: 6” X 4” X 5/16” ANGLE A36
Albina to roll all possible from each length (4” Leg in) to a 59’-1” outside radius.

5 lengths x 20 ft: C10 X 20# A36
Albina to roll all possible from each length (flanges out) to radii ranging from 52’-7” – 59’-1”.

3 lengths x 20 ft: 3” X 2” X ¼” ANGLE A36
Albina to roll all possible from each length (2” Leg in) to a 58’-11” outside radius.

2 lengths x 20 ft: 3” X 3” X ¼” ANGLE A36
Albina to roll all possible from each length (Leg out) to a 52’-7” inside radius.

Albina bent 10 lengths of 60-65 foot spans of wide flange W36 X 135# A709-50W the easy way to a radius range of 95 ft – 229 ft, depending on the length and section of the bridge. The Red Electric Bridge, located in Southwest Portland, provides pedestrians and cyclists with a direct, car-free link to the main streets of the area through a forested gulch.

The Architizer A+Awards is the largest awards program focused on promoting and celebrating the year’s best architecture and spaces. The award honors the world's best in buildings and spaces. Hayward Field has received the 2022 Popular Choice Architizer A+ Award in the Stadium and Arena Category. 

Albina Co., Inc. “The Front Runner in Steel Bending. We Tower Above the Rest” Albina Co., Inc. was thrilled to be an integral part of reconstructing Hayward Field at the University of Oregon. Hayward Field is the world-class home to @OregonTF. Hayward Field is an Award-Winning Project!

Albina created the curved steel diaphragm used to support the roof structure and provided various bent materials to help construct the landmark tower at the northeast corner of the facility as well as the jumbotron. Designers wanted to create a structure that was open and airy, allowing spectators to enjoy great views and natural daylight, in an intimate environment.

Pipe: Hayward Field Roof

We rolled 600 lengths, varying from 28’-0” to 75’-6” long, of 14" OD X .375" / .500 WALL A500-18 GRADE B&C. That is 1,500,000# lot weight (750 tons) of rolled steel, 32 inbound trucks and 90 outbound trucks.

Plate: Hayward Field Roof

The 14” OD material was laid over the top of the plate that we bent for this project. We bent 300 lengths, varying from 3’-0” to 37’-0” long, of PLATE 1½" THICK X 16¾" WIDE A572 GR. 50 and PLATE 1½" THICK X 10" WIDE A572 GR. 50.

In addition, we provided various bent steel parts for general field enhancement and utilities at the newly renovated complex.

Our work was extremely precise, and we had zero rejected parts by the fabricator, Fought & Co., Inc.  In fact, they also informed us that when measuring the work points during fabrication, they never once had to heat up or adjust the bending. To make the erection process go smoothly, we marked every 3-4 feet on the centerline back of the pipe to assist in the layout process for the diagrid “fish-mouth” stubs, and up-stands for the roofing system.

In addition to the iconic roof, the tower at Hayward creates a community landmark honoring the first 100 years of track and field at Oregon.

Hayward Field 187-foot tall Tower

We rolled 400 lengths for Alpha Iron, varying from 20’-0” to 60’-0” long, of Tube Steel 8" X 4" X .500" WALL A500 GR B, 8-5/8" OD X .625" WALL A500C WHEELED, 8-5/8" OD X .375" WALL A500C WHEELED, 8-5/8" OD X .250" WALL A500C WHEELED, and Flat Bar 3/8" X 4½" A36. That is 330,000# lot weight (165 tons) of rolled steel, 10 inbound trucks and 16 outbound trucks!

Hayward Field Jumbotron

Albina bent 101,000# total pounds for this project for Alpha Iron. We bent 43 pieces (20 lens x 50 ft:  10¾" OD X .375" WALL A500 GR. C) to various radii ranging from 5'-3" up to 224'-4" all to AESS standards. We bent 27 pieces (19 lens x 60 ft:  12¾" OD X .375" WALL A500 GR. C) to various radii ranging from 5'-11" up to 208'-8" all to AESS standards. We bent 3 pieces (1 len x 42 ft:  12¾" OD X .500" WALL A500 GR. C) to a 4'-6" radius all to AESS standards.

A project for the record books for sure.

The Buddy Holly Hall of Performing Arts and Science in Lubbock, Texas is a 220,000 square foot state-of-the-art campus featuring two theaters, event space, a full-service bistro and a ballet academy under one roof. Albina bent various materials for the signature spiral staircase in the Christine DeVitt Lobby. See the video below to get a sneak peek inside!

The projects is featured in the May edition of Modern Steel Construction. For more details on the entire project and to see a full list of winners check out AISC's website. 

TS 16" X 8" X .625" WALL A500 GR C
16 pcs: Spiral bend the easy way
Bent down to a 7 ft plan view radius.

TS 10" X 6" X .625" WALL A500 GR C
10 pcs: Spiral bend the hard way
Bend down to a 14' 11" plan view radius.

Albina bent 40,000# of steel for the steel tree-like columns and curved “steel” branches that create the biophilic-inspired archway entrance for the Freyer-Newman Center at the Denver Botanical Gardens. Albina bent 60 pieces of W8 X 31# A992 the hard way to a full scale layout. We also bent Tube Steel 8" X 6" X .500" WALL A500 GR B the hard way and MC8 X 20# A36 the hard way. The Freyer - Newman Center is a LEED GOLD building, designed by Denver’s Davis Partnership Architects. The Center houses six classrooms; four galleries; new herbaria for vascular plants, mushrooms and slime molds; laboratories; a new library and a coffee shop.
