I am analyzing a pier supporting 2 simple spans that are 45 degree skewed. 1. I am confused what offset needs to be entered in superstructure definition? 2. How is this offset playing a role in LL generation? I noticed that changing offset is changing…

I'm running a curved bridge in LEAP Concrete. The begin and end bents have different skews resulting in variable girder lengths. LEAP suggests running the, "Girder-by-Girder" analysis. However, when running this analysis my girder is failing, miserably…

I am designing a hammerhead pier using the substructure module in LEAP Bridge Concrete. The geometry is a little odd...it's a hammerhead cap on a circular column. To compare the results for the cap design from the conventional sectional design & strut…

I am using the LEAP Bridge Substructure module to design a pier for a continuous 4 span structure using HS20 LFD loads. In the AASHTO Standard Specifications, it gives you a few options for the loading. One is that you can use a lane load with one concentrated…

I am using the Substructure module of LEAP Bridge Concrete. According to AASHTO LRFD, you can't have a truck on both the approach slab and on the deck, but you can have a lane load on both. When generating live loads for an abutment, there are two…
