I am trying to investigate LEAP Steel as a viable option for Steel Design and have run into a few problems. I am currently working on a 3 span curved plate girder.
1. If I have multiple units within a bridge (2 bearing lines at a pier), is there a way to have the girder section end before the CL of Pier? I have offset the bearing and stopped the slab where I need to, but the member definition states that the girder section has an incomplete section. I do not want to include this additional length of girder section for bearing reactions.
2. Under Pier/Abutment locations, what is the intent of the "Offset to Bridge CL" option? My baseline is not centered on the bridge, so I assumed that I should enter a value here to offset the center of piers and abutments. Graphically this did not occur and the piers are still centered on the baseline. Also, it appeared to alter my span lengths when it came to member definition.
3. When defining crossframes, the graphics do not match the intent from cross-frame/diaphragm definition. I have defined my diagonals based on the top of the member. At the top of the crossframe the offset appears to be correct in the graphics. In the bottom of the crossframe, the offset is shown much larger than the input value.
Thank you for your assistance.
Hey Vinay,
Can you post your final response to Question 01 here, we also have a similar query. By default, LEAP Steel takes the beam length as span length (CL Pier to CL Pier). We have inverted T bents and need to end tub girders 3" from face of inverted T stem.
Thanks!
In the latest version of LEAP Bridge Steel one can define the Overhang in the Member Definition dialog.

Dilip,
The query is regarding longitudinal length, how to end the steel girders before CL Pier. I am quoting the original question below for your reference.
