RE: concrete box culvert

Yes: Frame analysis software and Microsoft Excel

RE: concrete box culvert

Agree with the first poster in that your best bet is a general frame analysis software coupled with MS Excel or MathCAD for the design portions.

At 18' (6 meters) span you're just at the limit for precast and you might be able to get a version of Boxcar.  However, be mindful that this for precast which generally uses higher strength concrete than is typical for cast-in-place field work.  It should get you in the ball park for preliminary design.

Check out CALTRANS website as they have a nice example for culvert design in their manual.  Other DOTs will likely have the same.

RE: concrete box culvert

Brass culvert is a nice option

RE: concrete box culvert

Many times your state or government transportation department will have pre-designed culvert plans available.  Have you tried with them?
 

RE: concrete box culvert

Why do you need a computer program for a simple job like that?  Why not do it by hand methods?

RE: concrete box culvert

Qshake, what do you mean at the limits for precast? I have done 3 sided culverts precast up to 84 foot span.  

RE: concrete box culvert

ztengguy, were they boxes, or arches? I've heard that Bebo precast arches can have very long spans, but I've never heard of precast boxes anywhere near that long.

RE: concrete box culvert

Agree with ACtrafficengr that anything with a span that long is a three hinged arch of the Bebo kind.

Or maybe you used 4 - 21' culverts side by side?

Most three sided culverts go up to mid 50' and certainly one reason for the lack of product above this isn't structural but weight related to shipping.
