I believe so. Zensteeldude or others more familiar with home construction might know more about this than I do.

Interestingly enough, I think the truss structures in the original WTC buildings (which supported the floors and connected the outer structure and the core) were called joists.

The original sculpture survived the collapse of the twin towers. It's currently located in Battery Park and will be returned to where it originally was once the Memorial is finished.

Do you mean exactly where it once stood, somewhere north of the museum, or near the freedom tower?

Funny, I'm reading a book about the history of Chicago skyscraper construction and they use all three terms, too. That's why I posed this question.

The new view from the obsevatory will be nothing like anyone could ever imagine!!! I am talking just in the year 2013 alone when it opens, I mean one will be looking down at not only what was other buildings there were to look at before including the WFC, The Woolsworth Building and others, but at the numerious spactacular additions that have gone up since 9/11/01 including the new 7WTC, 4WTC, Goldman Sachs, Beekman Place, W Hotel, and Barkely Street Condos!!! It will be a very romantic scene when one will dine at night in the new restaurant!!!

The sphere in its original location would just about sit in the middle of the new greenwich street. While it will almost definitely will return to the site somewhere, it won't be exactly the original location. While it did survive the collapse, it did come out damaged, and so it is much more likely they'll place it near the memorial as opposed to tower 1.

What's the difference between a girder and a beam?

Always bugged me...

Thx
dchan covered it rather well.

But if you really want to get technical,(I always do ) in steel construction, a beam is any rolled shape used in a horizontal position. A girder is any horizontal fabricated shape used in a horizontal position.

For example a Wide flange 44"x244 lb. rolled shape is a beam, a 24 inch I section made up from 3 plates welded together is a grider.

Yes, the big difference is wood joists are spaced 16" on center and steel beams are usually placed 5 feet on center. (Steel decking is MUCH stiffer than 3/4 inch plywood.)

In everyday use there are 3 kinds of beams that makeup the floor structure of a building, spandrel beams are on the outside perimeter of the building, floor beams run between columns on the interior and filler beams run between the floor beams.

And it's currently serving its days at Battery Park for anyone who wants to see it. It may or may not be returned to the museum.

It's already sneaking its way up the food chain. Come spring, people who never go Downtown will be shocked that its as far along as it will be. For so long this tower has been just a concept, but the reality is taking shape before our eyes.

And by the way, all of the photos of this tower under construction will become classics. Every day is unique. Never again will we see this tower in this form. Once built, it's built. But we were around to see it rise, and will keep that memory (along with the thousands of photos... )

Excuse my stupidity on this subject. So each floor/story is 13 1/2 feet?? Is that the "norm" for all buildings?? Also, 4 floors a month equals 1 floor per week...is that the right speed??? (it seems slow, but I have noooo concept of the amount of work going into this). I'm assuming the work going into this building is above and beyond any building codes because of what happened on 9/11.

Anyway.....thanks again to all those who contribute photos here. It's a great site that I visit a few times a day.

Most people don't have a clue, and it's extremely disappointing. To them it's just a hole in the ground.

I have this problem with people in Austin. I go to NYC a few times a year for work and try and swing by to see the construction and all of my friends think it is just a giant hole in the ground still.

I show them photos and explain it would already dominate our skyline were it being built here.
