Most civil engineering magazines (particularly structural) are received as a result of membership in a particular organization.
I'm a member of AISC (Amer. Inst. of Steel Construction) and I particularly like "Modern Steel Construction". It's my favorite. They showcase some really cool projects every month, and I'm really fond of steel design anyhow.
I'm also a member of ASCE (Amer. Soc. of Civ. Engs.) and they publish "Civil Engineering".
Zweig White also publishes "CE News" (
Welcome to CENews.com - For the Business of Civil Engineering) and "Structural Engineer" (
www.gostructural.com). They have some pretty good salary surveys every year, and they publish a list of the best firms to work for every year, too.
There's also "Structure" which is decently good (
www.STRUCTUREmag.org).
I also get "Spectra", but that's more of an academic journal from my EERI (Earthq. Eng. Research Inst.) membership. It's pretty cool, but others might not find it as interesting as I do.
