Hello,
I am trying to import my live loads into Leap Bridge Concrete from a text file. I am getting an error saying "Error on reading bearing loads!". However, when I import my temperature loads from a text file, I have no issues. The text files for each load type are setup the exact same. I was even successfully able to import my live loads from a text file when I selected other load types; I tried BR and TU load types and had no issues with either. It seems like the problem is isolated to the LL load type when importing the loads from a text file.
My version of Leap Bridge Concrete is 19.02.00.33
Thanks,
Zach
Please see the attached Text format for the LL bearing loads .
Bearing loads 1, 1, x, 1 1, 2, Y, -2 1, 3, z, 0 2, 1, x, 4 2, 2, Y, -5 2, 3, z, 0 1, 1, x, 0 1, 2, Y, -8 1, 3, z, +9 2, 1, x, 0 2, 2, Y, -11 2, 3, z, +12
Hi Vinay,
That is how my text file is formatted and it is still not working. I even saved your file and tried importing it in with no luck. I think the issue is not with my text file as it will import into other load types (BR and TU). I think the issue has something to do with the LL Load Type.
1) In conspan once the analysis is done please go to the file menu and click EXPORT TO RCPIER.
2) In the new window please save the file as a TEXT File .
3) Open RCpier and select the Dead Load-load case and click EDIT button -->Click generate --> Select option “ Input composite Dead Load reaction from conspan”.
4) Click IMPORT button --> select the conspan reaction file and click IMPORT button à finally click Generate button and you should be able to see the reactions generated on the bearing.
5) Please follow the same procedure for Live load – Load case too.

I realize this question is nearly 2 years old, but for anyone who may run into the same issue here is what worked for me. The text file format in Vinay's comment is incorrect for live load (at least in the version I am using, v20.00.00.58), and the article on importing live load forces from conspan is useless if you're designing a pier for a steel bridge.
LBC needs to know which forces are from the truck loading and which are from the lane loading (if present). It does not assume a type if you do not specify it, which generates the error. See the image below for the correct text file format.
