I am attempting to design a base plate connection for a HSS 3.5"x3.5"x3/16" Column. It is a cantilevered awning that is creating a rather large moment about the base. I calc'd that I would need a 3/8" fillet weld around the member to resist the moment, but the 3/16" thickness of the HSS column...
Hey guys,
I just have a general question about drawings. I have a road with an S-Curve. The existing road was built along a section line, however, it is a local road that was built offset from the section line. At the other end, it is the exact same deal, just offset to the other side...

Hi all,
I was thinking about how the minimum slopes came to be in the 10 states standards manual for storm and sanitary design criteria. Does anyone know how the slopes that are used came to be? How do we know an 8-inch sanitary line needs a minimum slope of 0.4% and not 0.35%. Just a thought...
Hey guys,
Anybody know of a good distributor to get a lot of KMnO4 powder from. I'm doing a cost analysis on leachate treatment right now and after some tests this was the best option but it is apparently not worth the hole in the wallet.
On a side note, any other recommendations for treating...
I am currently having trouble covering a manhole, cue to all these extra little things I have to worry about. I have been racking my brain for a solution and have looked through way to many catalogs. Here are all the things I am worrying about:
