Beam Design formulas

One of the good things of Internet is the wealth of knowledge you can find available at your fingertips. The two bad things are first that this knowledge is difficult to find and second, you can not always trust what you find.

The American Wood Council has a very interesting site with good and useful information. Although not specifically related to bridges, one of the documents for free download has beam design formulas with shear and moment diagrams, as well as deflection calculations.

I have not used those tables for a few years now, but when I was doing some design and analysis, I found them very useful and very difficult to find. I always seemed to need the case they did not include.

I would recommend to download that document and browse the rest of the website, as I said, although not specifically related to bridges, still very interesting
