Steel may seem like a standard material in skyscrapers, office buildings, schools, and big retail stores, but it can be manipulated to create intricate structures and architectural wonders. Check out these eye-catching buildings created with structural steel:
1) Nascar Hall of Fame | Charlotte, North Carolina
Steel trusses are used to achieve significant spans in the project:
- A set of trusses spanning 175 feet achieve a grand column-free ballroom
- A 100-foot-long, bi-level footbridge, supported by a pair of one-story-deep trusses, links the ballroom with the existing Charlotte Convention Center
- Two- and three-story-high trusses cantilever 30 feet over the broadcast studio.
2) City Creek Center Retractable Roof | Salt Lake City, Utah
The resulting retractable, barrel‐vaulted roof is configured in two sections, each spanning one city block:
- Each section is 240 ft. long and 58 ft wide, with an S‐shape that echoes the curve of the signature City Creek
- The precision‐sculpted steel and glass transparently shields patrons when closed, and disappears from sight when open; connecting nature with the areas below.
3) Bird’s Nest | Beijing, China
- 110,000 tons of the steel were used in this structure built for the 2008 Beijing Olympics.
- “In China, a bird’s nest is very expensive, something you eat on special occasions.”- New York Times
- According to Reuters, more than 17,000 people worked on this one stadium alone
Gateway Arch | St. Louis, Missouri
- The Arch is made of 142 stainless Steel Sections
- The structure was built as a monument to Thomas Jefferson and all those pioneers for who St. Louis was the Gateway to the West
- The Gateway Arch is made of steel and concrete
- Double wall construction with 1/4” stainless steel on the outside and 3/8” structural steel inside
- The distance between the wall or “skins” at the surface is 3 feet, narrowing to less than 1 foot at the top
- There is a layer of concrete between the skins approximately half way up the legs of the Gateway Arch
