Several Question regarding Leap Bridge (Conbox or Conspan)

Conbox——CB

Conspan——CS

  1. In the CB/CS,  these is no place to fill in the lane info, like width of lane, amount of lane, lane location (eccentricity to the ref line of bridge/center line of bridge),
    How the Leap CB/CS calculate these parameters?

    E.g. I have a multi-span continuous bridge with 19.4m wide, four lanes: 4x3.7m, the left and right overhang are 3.2m and 1.4m, respectively.
    Apparently, the bridge can hold 5 lanes with 3.7m width of each lane. How can I confirm that CB/CS only use 4x3.7m lanes instead of 5x3.7m?

  2. The bridge in the above example should hold one owner specified military truck on on lane, for the rest of the lanes, HL-93 should be used.
    I find there is a side-by-side option in CB/CS live load option, which corresponding to AASHTO LRFD 2010 #4.6.2.2.5.

    I need to know in detail how to use the side by side option in CB/CS?

    Below is my side by side config, please correct me if I'm wrong,

    Create a new live load group, I call it "Milltary Truck Side by Side" under Loads/Analysis tab,
    Define a new Military Truck in live load definition windows first,
    on the top right corner of the above window, there is a drop down menu for side-by-side, select "Lib:HL-93 Multi-span".
    Apply "Milltary Truck Side by Side" to the liveload case.

    I want to make sure what I have done as shown above is correct for my bridge.
    I only use the created "Milltary Truck Side by Side" in the live load cases, do I still need to apply "HL-93 Multi-span" in the same live load case as well?

  3. In the above side-by-side definition, I use HL-93 as side-by-side load?
    What the difference if I create a new "HL-93 multi-span" live load, then select "Military Truck" as side-by-side load?

    The  design work is urgent, please help.
