    FINDING DECK BENDING MOMENTS FOR WHEEL LOADS

    "Everything else looks right, just plug and chug, it's empirical." Thanks Koodi, that was the answer needed (I did not want to complicate my question with issues of determining span, load combinations, etc. Those are all clearly given in the code and not the problem. I think it's hard...

    FINDING DECK BENDING MOMENTS FOR WHEEL LOADS

    Qshake, thanks for the reply. I've read many of your's in the past and you are a great resource. I really could use someone specifically addressing the code articles I sited, in order to be able to get through a particular problem tomorrow. Any advice out there?

    FINDING DECK BENDING MOMENTS FOR WHEEL LOADS

    (I posted a similar question in AASHTO forum) Reality check is requested by engineer who doesn't often stray into the AASHTO code. I want to find the design live load bending moment in my rc deck with main reinforcing perpendicular to traffic. Following 3.24.3.1: S=10 ft span between...

    BRIDGE DESIGN SPEC: concrete slabs bending moment

    Mike, thanks for responding. Have you used these in practice? Can you verify that I'm applying these correctly if I use them as follows: for 3.24.3.1: S=10 ft span P=16,000 lb M = ((10ft+2)/32)*16,000lb = 6,000ft-lb per foot-width of slab For 3.24.3.2: S= 10ft P= 16000lb E= 4+0.06*10 =...

    BRIDGE DESIGN SPEC: concrete slabs bending moment

    Please shed some insight for me on the application of 3.24.3 In 3.24.3.1, "Case A-Main Reinforcement Perpendicular to Traffic". The equation given returns a moment in "foot-pounds per foot-width of slab". Is it to be multipied BY THE SPAN LENGTH to find the moment in the...

    Design by rule of thumb

    Two rules from carpentry: "Measure twice and cut once". That should be self-explanatory. "It's not wrong until it can't be made right" ie: many mistakes can be fixed before it's too late. Example, changing rebar before placing concrete.

    Golf-Cart bridge

    A GOLF-CART BRIDGE: Should it be designed as a pedestrian/Equestrian/Maintenance Vehicle Bridge, with pedestrian Live Load and H10 vehicular load, or should it be considered a vehicular bridge? What design loading/load combinations apply for this kind of structure, specifically as a short...
