Well, then I guess industry standard assumes that "self-supporting structure" is the same as a "free standing structure".

I was reading the TIA-222G manual and it said that Section 2.3.2 Strenght Limit State Load Combinations 1. 1.2 D + 1.0 Dg + 1.6 Wo 2. 0.9 D + 1.0 Dg + 1.6 Wo 3. 1.2 D + 1.0 Dg + 1.0 Di + 1.0 Wi + 1.0 Ti 4 1.2 D + 1.0 Dg + 1.0 E 5. 0.9 D + 1.0 Dg + 1.0 E Exceptions: 1. Temperature effects need...

STAAD is a software that's capable of running both first order and second order analysis. Second order analysis accounts for small and big delta. You can go to http://youtu.be/3lmXNN587Y8 for a review of Staad's direct analysis. Note, Staad 2007 doesn't have small delta effect turned on by...

Have you thought about creating an awesome product that you can sell? Or maybe even perusing the EE patents and improve existing designs and patent it yourself? If you're financially independent and sustainable w/o being employed, wouldn't it be awesome if you became your own boss? Maybe I'm...

pra713, it's good that you're giving your major a second thought but please consider the following things: 1. Make sure you're giving up on Civil Engineering because you have no interest in it at all. Make sure without a doubt that it wasn't regret that's that driving force for abandoning the...

Reading this post gave me significant insight. After some online searching, this source, www.safety.rochester.edu/ih/pittrain.pdf, page 21, says that a 5,000lb forklift with a 4,000 lb load driving at 10mph can deliver 135,000 lb of destructive energy. That would cause tremendous shear at the...

Hi, I'm a structural eit and I have a lot size that's 80' x 280'. I need at least 300 parking spaces indoors, but because the building is so narrow, it would prove uneconomical for indoor ramped parking. I tried a few configurations already, and for 300 cars, I'll need to go up to 8 stories...

Yes, in this kind of economy, I can understand how important job security is. Talk to your wife and see what she says. The trips really aren't that long, 1-2 trips for 2-3 days per month is really not a lot of travel. Just make sure you get something in writing that they're going to hire you...

If you want other people to take a look at your Etabs file, I think you need to provide them with the .edb file and not the .e2k file. Please correct me if I'm wrong.

What you can try to do is to go to Google books and do a search on ACI 318. They have ACI 318-05 listed there. Because it's a limited preview, you will most likely have to pick your pages carefully. This means: 1)go to books.google.com 2)search for "aci 318" 3)the search results will give you...

If you refer to the ACI Code 2008 Index, page 460, look under Concrete and you will see the minimum strength requirements at different sections. See 1.1.1, 5.1.1, 19.3.1, 21.1.4.2, 22.2.3 Nonetheless, from 5.1.1, it states: Concrete shall be proportioned to provide an average compressive...

Thanks for the correction StructuralEIT. Sorry to WillisV for asking for clarification. Also to all people who were reading this thread, ignore the part "(since D=0, (D+L)/240 = (0+L)/240)". Just one question to StructuralEIT. Do you check l/360 or l/240 for interior steel floor members...

Hi WillisV, you said that you would use L/360 for live load and L/240 for (dead + live). Please clarify on L/240. Do you mean (D+L)/240? And do you mean that you'll check both as well? Thanks.

Thanks so much! Can't believe I overlooked that!

I remember coming across a post in Eng-tips forum asking about an ambiguity in footnote "g" of Table 1604.3 of the IBC 2006 code. Unfortunately, I couldn't find that thread anymore, so I'm just giving that person a heads up on my finding, as I too, have found this to be very intriguing...

"Wind and Earthquake Resistant Buildings" is a book that I am currently reading. It is authored by Bungale S. Taranath. When I came across page 9 of the book, I found the following example: f = V x S /D The formula, is supposed "...to calculate the frequency of the transverse pulsating...
