Steel Structure Trivia: Campus Hangout
Posted by Tasha Weiss on February 28, 2014 at 1:01 PM.
Here’s MSC’s February Steel Structure Trivia question! The above photo shows one of the more than 150 AISC steel sculptures located on college and university campuses around the U.S., designed to be a visual teaching aid that shows students a variety of members and connections (and most have been donated by local fabricators). Your trivia question is: Where is this steel sculpture located?
This steel sculpture is located on the campus of Kansas State University in Manhattan, Kan. Clad in the royal purple shirts (KSU’s official school color) are officers and advisors from the Structural Engineering Association of Kansas and Missouri (SEAKM). Photo: Courtesy of KSU
Congratulations to our winners: Christopher Cichon, a structural associate at Sargent & Lundy in Chicago; Manop Kaewmoracharoen, Ph.D., a civil engineering professor at Chiang Mai University in Thailand; and Barbara Monroy, a structural engineer at Black & Veatch in Overland Park, Kans.
The sculpture, titled “Ad Astra E Terra,” was donated in 1988 by then Havens Steel Company. Located on the northwest side of the university’s Seaton Hall, it is dedicated to the Department of Architectural Engineering and Construction Sciences for the advancement of education in the design and construction of steel structures.
Originally created by Duane Ellifritt, professor emeritus from the University of Florida, the AISC Steel Sculpture was designed to be a visual teaching aid that shows a variety of members and connections. It consists of 25 steel members, 43 connection elements, more than 26 weld groups and more than 144 individual bolts.
You can see if a school near you has a steel sculpture on the Faculty and Students channel of the AISC website.
To find out how to get a Steel Sculpture on your campus, please email Maria Mnookin at firstname.lastname@example.org. Fabricators interested in building and donating a steel sculpture to a university should also contact Maria.

Steel Shots: Steel Sets the Stage in Sochi
Posted by Tasha Weiss on February 24, 2014 at 2:06 PM.
The Sochi Olympics opening ceremony featured a majestic scenery of seven floating islands representing various regions of Russia. Steel truss framing was used to support the foam cladding and visual scenic elements on the islands, built mostly out of HSS 2-in. by 1-in. by 1/8-in. ASTM A500 grade B steel. The above photo shows the steel framing used for the island representing the forests of the Urals. Click on the photo for a view of the complete island as seen during the opening ceremony.

The Sochi 2014 Winter Olympics have come to a close, but here’s a look at how steel set the stage for the ceremonies at Fisht Olympic Stadium.
Built primarily for the Sochi Olympics and Paralympics, serving as their Olympic Stadium, the 40,000-person open-air stadium boasts one of the largest indoor stages ever build, covering the entire stadium surface at around 120,000 sq. ft. Composed primarily of wide-flanges beams and HSS tubes, the total stage structure weight adds up to a staggering 2.7 million lbs.
Show Canada was given the mandate to design, manufacture and install the main stage and scenic elements for the ceremonies of Sochi’s Olympic Games. “The engineering department was required to design and engineer all of the structural elements according to the AISC Steel Construction Manual LRFD / AISC 360-10,” said Jean-Philippe Major, engineering director at Show Canada.
The seven floating islands representing different regions of Russia, from the Kamchatka volcanoes and the forests of the Urals to icebound Lake Baikal of Siberia, were a part of the major canvas of the Olympics opening ceremony.
The main engineering challenge was to design an optimized light steel truss framing to support the foam cladding and visual scenic elements present on the islands, said Major. The frames were built mostly out of HSS 2-in. by 1-in. by 1/8-in. ASTM A500 grade B steel. Furthermore, the maximum allowable load of 2,400 lb. per rig point (four rig points total per island) was one of the main difficulties in the structural design of these very artistic scenery elements. Special connection between trusses for easy assembly and shipping were designed and engineered using Finite Element Analysis (FEA) and manual calculations to ensure the islands’ structural reliability.

Steel Work Complete for Haiti Health Center
Posted by Tasha Weiss on February 19, 2014 at 6:34 PM.
The new Gheskio Family Health & Nutrition Center in Port-au-Prince, Haiti, has reached a significant project milestone: The steel frame is complete. It was erected by Haitian workers together with a small American crew.
Designed by NYC-based firm Tonetti Associates Architects, the new health center represents GHESKIO’s comprehensive approach to nutrition, clinical care and community development through combining various healthcare and family planning departments within a single complex.
The design team undertook this project as an opportunity to help the people of Haiti after the devastation they experienced in the Haiti earthquake.
“We chose a steel frame building because of the lower mass of the building as compared to the standard Haitian concrete and masonry construction, and because of the great control of the detailing of the structure,” said Andrew Wright, AIA, LEED AP, of Tonetti Associates Architects.
Construction is expected to be complete this fall.
A August 2011 MSC article entitled “Assurance of Quality” discusses the project team’s choice of steel for the health center, written by Charles J. Carter, S.E., P.E., Ph.D., AISC vice president and chief structural engineer.

Engineers Week Kicks Off
Posted by Tasha Weiss on February 17, 2014 at 5:12 PM.
National Engineers Week commenced yesterday and runs through Saturday, February 22, with various educational and celebratory events that provide interactive experiences with engineering.
For example, the Chicago Architecture Foundation (CAF) kicked off its slate of week-long events yesterday with an all-day festival called “Engineers This! Building That!” designed to help families discover what engineers do by providing educational presentations, demonstrations and hands-on activities emphasizing engineering related to buildings and structures.
Hundreds of children, students and adults attended throughout the day and were able to meet engineering professionals from around the region, including volunteers from the Structural Engineers Association of Illinois (SEAOI), and learn about the work they do to shape our cities, as well as participate in various activities which included: constructing skyscrapers using LEGOs and testing them in a simulated earthquake (as shown in the top-left photo); discovering the building materials of structures (including steel!) and innovative systems like shear walls and how they resist earthquake and wind forces; and designing their very own bridges (as shown in the photo at right).
Other events offered by CAF this week include a tour tomorrow of the steel-framed Willis Tower to explore the unique architecture and structural design of this famous Chicago building, an adults-only LEGO skyscraper competition (judged by SOM’s Bill Baker) with cocktails on Wednesday hosted by the Architects from the Council for Tall Buildings and Urban Habitat, and an engineering day for teens on Saturday at Crown Hall, where they’ll be able to engage in structural design challenges with practicing architects, engineers and other designers.
Now in its 63rd year, National Engineers Week is organized by DiscoverE (formerly the National Engineers Week Foundation) whose mission is to help unite, mobilize and support the engineering and technology volunteer communities.

Whether you’re single or attached, it’s hard not to love Times Square’s heart-shaped, red and pink architectural sculpture, called “Match-Maker,” designed to cosmically connect people this Valentine’s Day–and supported by structural steel.
Designed by Young Projects, a Brooklyn-based multidisciplinary design firm, Match-Maker was chosen as the winner of this year’s annual Times Square Valentine Heart Design by Times Square Arts and Van Alen Institute. It was unveiled on February 10 and will remain on view for one month at Father Duffy Square, between 46th and 47th Streets.
This interactive installation is made of powder coated aluminum tubes. Each tube is a custom piece, varying in length, angle and color. The aluminum periscopes are each suspended by a series of powder coated brackets that attach to a single steel column.
Visitors arrange themselves at twelve points around the heart-shaped sculpture. Peering through colorful, interwoven periscopes provides glimpses of each viewer’s four most ideal astrological mates, offering potentially novel connections between lonely souls or settled lovers. The form of the sculpture is elusive, complex and symmetrical, and changes as viewers experience it from different vantage points throughout Times Square. From many points of view it forms a perfect and iconic heart; from other perspectives the sculpture is tangled and perplexing.
For the past six years, the Times Square Alliance has invited architecture and design firms to submit proposals for a romantic public art installation celebrating Valentine’s Day in Times Square.
