Hello,
A client is requesting I test a bridge with the following parameters:
Is it possible to model a LL like that in LEAP Steel?
When I define the LL, I choose my permit vehicle with no load side-by-side. However, the lane loading details report shows that multiple lanes are loaded simultaneously with the same permit vehicle.
I've thought about constraining the roadway width to where only one lane is loaded and floated by the program, and run multiple models manually floating the roadway width thus covering the whole bridge, but my model is already taking over an hour to process so I figured I could ask for some advice on this.
Thanks!
In the Live Load window for permit load do not select "include Lane load" and then for " Side by Side option" Select as NONE.
in the lane setup window , user can select FIXED lane layout and then set the OFFSET from the left and right edge of the deck.
Vehicle path : center.
For more information where the lane loads are located , please check the below mentioned Bentley communities link.

Please let me know if this is the information you are looking for.
Please let me know if you need any additional information.

Vinay, thanks for your reply.
I had defined the truck as you suggested. My bridge is very wide and it can fit 7 lanes fixed when the OFFSET is not reduced. So:
1) If I fix the lanes with and reduce the vehicle path to only have one lane, I would have to run multiple models so that I can "manually move around the one lane" along the width of the bridge
2) If I don't reduce the vehicle path with the OFFSET entry, the program floats the lane for me. However, it places multiple trucks simultaneously even when the Side-by-side option is set to None.
It seems like there may not be a way around this.
You are welcome.
The workaround solution is to run multiple models so that you can manually move around the one lane along the width of the bridge.
