  • LEAP Substructure - Full height abutment on piles - footing reinforcement design

    Hi - I'm designing a full height abutment and wingwalls on a shared footing supported on piles. LEAP has calculated an extremely large design moment and I can't quite back into the number. Can you explain how the software determines the maximum design…
  • Thermal cyclic loads

    I'm attempting to simulate how thermal loads may affect the backfill behind an integral abutment by deploying PLAXIS 2D. I modelled the concrete bridge deck as a Linear Plate element and included a prescribed displacement near the top of the abutment…
  • Adjust Cap Ends for Skew

    Can anyone explain what the "Adjust cap ends for skew" check mark does in "Edit Bearing/Step" for Abutment design in LEAP Concrete Bridge?
  • OpenBridge Concrete Substructure - Pile Reaction Calculation

    Hi, I'm working on an abutment design and am trying to check pile reactions using the bolt/rivet theory as described on the RM Wiki page: Abutment Design -- Pile Reaction calculation I have 2 questions: 1) I just wanted to quickly confirm the formula…
  • Bridge Grading around End's of Abutments?

    Good Afternoon Bridge Experts, Here at my organization internal bridge design is rather simple, we don’t design anything big or complicated mostly single span with concrete or steel beams. And when we have created designs the approach has been for the…
  • Openbridge Wingwall with backwall option

    It would be a great addition if we could create Wingwalls similar to the abutment cap with a Backwall offset option like this picture. Right now we have a workaround to create it with barrier but it would be a lot easier to add an offset parameter similar…
  • Apply 3D by Slope to Target

    The Apply 3D by Slope to Target from the 3D Geometry Tab in the Civil Ribbon Tab is very useful to adjust Terrain models near the bridge abutments . Users can rearrange the terrain slope to match a reference and create models adjusted to reality. Basically…
  • Special Abuttment

    Hi everyone! A user wants to create a special abutment, that is very common around here, see image The last beams are not supported in the ground, but in this special abutment and a set of columns that are buried by the fill material. The user…

  • Can I create a cantilever girder in LEAP Bridge Steel

    I have a multi-span bridge to be modeled in LEAP Bridge Steel. The bridge doesn't have abutments and it has two cantilever girders at two ends. Is it possible to create this model in LEAP Bridge Steel? Thanks a lot in advance
  • OBM - Curved abutment face

    Hi Bentley Community, Is it possible to create an abutment with a curved face in Openbridge? Thanks Oliver
  • OpenBridge Abutment

    Why is my abutment not full length in relation with the deck?

  • RCPier - Spread Footings on Rock vs Soil

    Hi there, I'm checking a design calculation for an abutment on spread footings done in LEAP RCPier. I couldn't find any information in the user manual or input/analysis tabs to determine how bearing pressure is calculated for a wall bearing on soil…
  • RC-PIER Material Properties tab

    I'm designing a pile cap abutment in RC-PIER, but I'm unsure how to input the material properties. In the material properties tab, there are inputs for concrete cap, concrete footing, and concrete pile. I have a concrete cap on steel H-piles. RC-PIER…
