    looking for product (Winn Viscotec)

    I am looking for a product that I used about 7 years ago. My recollection is that the product name was Viscotec and it was made by a company called Winn. My need is to find a suitable lubricant for pin & hanger on a bridge. The product was sprayed on (out of an aerosol can) initially had the...

    Operating Rating Level - interpretation

    We do not design bridges for specific trucks, but you can rate them for specific trucks. To answer your question (I hope), It will be up to the owner of the bridge if they will allow you to use the operating loading. If calculated correctly, the bridge can safely handle the operating load...

    Trail Bridge Design Criteria?

    I think the best information on timber trail bridges can be found through the US Forest service: http://www.fs.fed.us/na/wit/ At minimum, you will probably want to look at the trail bridge catalog: http://www.fs.fed.us/na/wit/WITPages/bridgecatalog/ And their free publication on Timber...

    Exodermic decks

    An exodermic deck is essentially a thin concrete deck poured on top of a steel grid deck. The two act compositely together. They tend to be lighter than traditional RC decks. For more information on cost, I'd contact: Exodermic Bridge Deck, Inc 60 Long Pond Road Lakeville, CT 06039 860-435-0300

    Prestressed Girder Replacement

    If you are using box girders placed adjacent to each other, use post-tensioning in the lateral direction; otherwise use sufficient diaphragms to ensure the bridge acts as a single unit thus preventing differential deflection.

    Existing bridge as form for slab bridge.

    Are you are using it as a deck replacement? When you add the new deck, you'll be adding a lot of dead load to the existing bridge. Are you trying have the deck act compositely with the bridge as a strengthening measure? The cast-in-place deck will only help with live load. the existing bridge...

    Existing bridge as form for slab bridge.

    I'm a little confused, are you using the existing bridge as form/shoring for the new slab? Aren't voided slabs usually precast thus eliminating the need for formwork? Why not rip out the existing bridge, drive your piles build a cap and drop in some precast voided slabs (I assume were talking...

    IS IT TUNNEL OR BOX CULVERT?

    The main distinction beween a culvert and a tunnel is that a culvert is a drainage structure under an embankment, while a tunnel is an underground passage. What you have is a tunnel. I have been told that there is no design code for tunnels. Good luck.

    Vehicle Impact Loads on Stationary Structures

    This problem is more complicated than it seems because the load on your gate will depend heavily on its stiffness and how it compares to that of the vehicle hitting it and the posts. It's really an energy/work dissipation problem Work (energy) a function of force and distance. This has to...
