When manually inputting live loads into RC-Pier, how do you specify a lane load. According to the help.... "For manually input live loads in AASHTO LRFD, this screen behaves slightly different. When a live load case is added in LRFD mode and edited, the program fills the bearing loads list. This contains two sets of loads. The first set of bearing loads corresponds to truck loads and the second set corresponds to lane load part of Design Truck loads. Initially, all these loads are set equal to zero. Users can only modify loads for this case but cannot delete the entries. To apply a truck load, select the corresponding bearing location within the first set, edit the load value, and click Modify. To specify a lane load part on a bearing, scroll down in the list and select the bearing location in the second set of loads and update it. To remove a previously specified load, set that load equal to zero."
BUT, when I try to add a Live Load, the Bearing/Girder loads are not filled out like they are supposed to be, see attached image. After adding loads there is no way to check the Lane Load checkbox. The only way I can get this box checked is to generate the live loads and then modify the data as needed. Unfortunately, if I want more load cases than the generator creates, I am stuck. Using the copy button will copy the live load, but all the lane loads inputs are left out of the copy.
Does anyone know how to get this "feature" to work???
Using RC-Pier 13.00.00.68
DPE, please email me your phone number (dilip.matange@bentley.com) and I can call you and explain different methods.
Hi - when I was trying to define live loads manually, I am not able to click on lane load option. I was wondering if you could help me how to set my live load as lane load.
When the loads are generated manually, one cannot turn the check mark for lane load. The first set corresponds to the truck loads and the second set corresponds to the lane loads. In both manual or auto generated loads, the program appropriately applies impact factors when the analysis is performed.
