The Amsysco Post-Tensioning Blog, one of the entries in the 2015 Best Construction Blog competition, shows how technical and specialized topics can be effectively covered in a blog — with content that provides challenging details and information, yet with an often-lighthearted and human-touch spirit.
Consider, for example, this recent posting:?Strength of Post-Tensioning:
Within the reinforced concrete construction industry, it?s widely known that a 1/2-inch-diameter post-tensioning tendon can hold around 27 kips (120 kN) when in tension. 1 kip equals 1,000 pounds-force and 1 pound-force equals the gravitational force exerted on a mass of 1 pound on Earth?s surface.
Fair enough — but what can that tendon hold:
How about:
- 12,258,000 U.S Dollar bills
- 109,367 Apple iPhone 5s smartphones
- 67,500 Rubik Cubes
- 43,200 bags of Lays Classic potato chips (10 oz.)
- 4,376 Sony Playstation 4 sets
- 3,375 Harry Potter paperback box sets (shipped weight of books 1-7)
- 200 Fish Tanks (including a few fish and flora inside 10 gallon of water)
- 89 GE Side-by-Side 21.9 cu.ft Refrigerators
- 9 Toyota Corolla (2014 curb weight)
- 5 Tesla Model S (2014 curb weight)
- 1 Dallas Cowboys endzone Jumbotron (a sideline jumbrotron needs 7 PT tendons)
So, it seems, the only thing on the above list that can beat a?1/2-inch-diameter post-tensioning tendon would be something like this:
“Mitsubishi really wants to make sure we get it right when we talk about the gigantic screen hanging from the roof of Dallas Cowboys Stadium this Sunday when the Super Bowl kicks off. In years past many of the stadiums where the biggest game of the year we held used a Jumbotron to show plays and other content during the game.
Cowboys Stadium has something better than a Jumbotron, a massive Diamond Vision display. The Diamond Vision screen is so gargantuan that it set a world record back in 2009 when it debuted in the stadium for the world’s largest HD display.
A few key facts about the screen include that the center sideline displays are 160-feet wide, 72-feet high, and have a screen area of 11,393 square feet. The gigantic screen consumes 635 kilowatts of power and weighs 1.2 million pounds. The smaller end zone screens are 1,493 square feet each. The screen is certainly very cool, just don?t call it a Jumbotron.”
It’s fun to make something technical and serious interesting. And this qualification certainly justifies recognition of the Amsysco Post-Tensioning Blog as a worthy entry in the 2015 Best Construction Blog Competition.
