Thanks guys. The application is for a stand for a 200 kip rotor to be serviced. I found a company who can bend up to an S10x35 beam to my radius, but I'm thinking this may overstress (prestress) the beam too much. What do you think?

Thanks JAE! That second link worked perfect!

Does anyone know if it's possible to manufacture a steel I-beam in the shape of a circle with a horizontal radius (flanges are at top and bottom) of about 2'-6"? If so, could it be rolled like that or would each flange and web need to be cut separately and welded together?

Does anyone know if special inspection is required under CBC 2007? In other words is using the full stresses still optional? Does special inspection need to be specified in the plans?

OK, thanks.

What is the significance of the dimensions based off the front axle?

I have the specifications already bridgebuster, but I don't know what the spacing is between the two rear axles for example. Or waht the 2'3" and 4'-6" means.

Does anyone know the axle spacing between any one set of axles which produce the 48 kip loading? Or if not the spacing then what does the 2'-3" and 4'-6" signify on the top right side of the sheet in the Caltrans Bridge Design Specifications?

I'm analyzing a bridge with an AC pavement over corrugated steel deck. Does anyone know the strength properties of AC pavement spanning over beams? In other words I need to find the shear and bending strengths of the deck.

Does anyone know the O.C. spacing between the 2 outer tires on either side of the rear axles?

Thanks everybody, I think I have enough info to continue my design.

Thanks for the links, but I can't seem to find any info on the z-beams.

Does anyone know where I can find a good source on light gage steel sections, particularly z-beams?

I am analyzing a bridge with rails on it from the 1920s. The rails sit on I-beams, but I don't know anything about the rail strengths or physical properties. Can anyone point me in the right direction as far as a 7"-128# groove girder rail?

Thanks for the link nutte! It looks like exactly what I need.

Thanks alot nutte! It looks like the "B" beams are the correct ones. Does it also give the Ix or Sx values for the B67? And is there allowable stresses given; flexural, shear, bearing, etc?

I have a bridge that I'm analyzing for a heavy load. The bridge was designed back in 1926! Two different I-beams are called out. They are a 10I22.4# and a 15I42.9#. Does anyone know where I can find the dimensions and properties of these sections?

Thanks for all the info guys. And the application is actually a bridge bent that is being constructed to test on our seismic shake table. We just didn't want to wait the 28 days for the bent cap to cure if we don't have to.

Does anyone know any disadvantages of using type III cement (cracking, etc.)? I'm about to be in a time crunch and I don't think I'll be able to wait the 28 days to gain the strength I want.

Does anyone know the maximum square footage for a slab-on-grade before score lines are needed to prevent cracking? The application is a foundation for 2 calcium nitrate tanks. A construction joint will be provided around the perimeter of the tanks. It's just around the outside of the tanks...
