Multi-Span Steel Girder Design Programs

[OneHotYoda]

Are there any multi-span steel girder design programs available online?

My bridge is located in Pennsylvania, but PENNDOT's steel girder program will only analyze multi-span bridges, not design them.

I don't need the program for final design, just a quick and dirty approximation for preliminary design.

I downloaded the SIMON program from AISC, but I've never used it before and every time I tried to run it, it would hang up. Also, judging from the input, it didn't seem like it would design multi-span bridges.

I see that MDX has a free 15 day trial, but I've never used the program before and am not sure of it's capabilities.

Thanks!

MDX, Merlin dash, maybe descus. I'm sure there are a few others

Thanks BridgeEI. I will check them out.

The best steel girder bridge program that I have used is MDX. The results from actual strain gages on a curved girder bridge were very close to MDX output.

Thanks edward1. I will look into it.

You can just use penndots program to analyze the beam-start with spam to depth ratios of web then with recommended flange plates based om aashto
