How does changing the values in A/D Parameters Cover section affect the analysis? How does this setting/section differ from the Bar distance input when doing a rebar design. Thank you

Hi If we define bar length, is leap bridge software have capability to deduct development length based on dia of bar and calculate flexure check at that point.

Is there a way to place two bearing pads per beam location as shown below?

In LEAP Bridge Steel, the Live Load Report for Moments and Deflections gives displacements for Y and Z (no X). What are these directions? Do the match the global coordinate system, which seems to be Y = vertical and Z = transverse? I'm doing a finite…

I have a cross frame with a WT shape for the top strut. Based on the screenshot below, the program seems to be orienting the shape with the flange along the bottom instead of the top. Is this something that can be changed? Thanks

I am pretty new to using Leap Bridge Steel, and have a question regarding a project I am working on. I have attached a general framing plan, and was wondering if Leap Bridge Steel was capable of modeling it, mainly due to the partial length girders. The…

Hi I am referencing in OBM model of a bridge into another file. However I notice that I am no longer able to see the bridge components in the open bridge model tab in the explorer tab in home ribbon. I sometimes encounter error that active bridge…

Where can I find the live load deflections including impact. I looked at the help window and the calculations are outlined. Can I find the calculations for my model somewhere? When I print the deflections, it only tells me release, erection, etc. It also…

I modeled a 4-span bridge as a single unit but now I need to update the model to add a unit so that each unit is 2 spans. Is there a way this can be done without revising the entire model?

The bridge I am working on has 4 splice locations at each member. For some reason, after running an analysis, the first and last field splice do not appear to be updated and the program is still prompting me to run an analysis at those locations before…

Is it possible to design post tensioned straddle bents in OpenBridgeDesigner/LeapConcrete? If so is there any tutorials on how to perform the design?

I have a model of a pier wall on pile cap. When I auto-generate the WS loads, I find that the column loads are applied between the top of the pile cap and the ground surface; that is, underground. Strangely, the load is the correct value (as if the wind…

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…

In Leap Bridge Steel, I have a curved bridge, so the girder lengths are not integer values. Under the Member Definition tab I'm unable to manually input flange plate lengths to a sufficient decimal in order to be able to run analysis (see below for the…

I have an OBM model built in a separate 3D file (File A). I referenced that dgn into a new dgn (File B) to create multiple drawing and sheet models. I have created mutliple 'drawing' models within File B with no problems. However, for the past few days…

I've an OBM 3D bridge 'design' model setup file 'SteelBridgeReplacement.dgn'. Using this file I have created mutliple 'drawing' models (Plan, Elevation, Typical Section, Pier Geometry, etc.) in a separate file (planProductionBase.dgn) by referencing the…

I am working in LEAP through the OpenBridge Designer BIM workflow. I have changed the concrete strength for an element in OpenBridge Modeller, but it isn't updating in LEAP Concrete. Please advise. OBM LEAP

Hi, I would like to know how to move the strands inward. I have not found a way to move the strands horizontally. I know how to do it vertically, but not horizontally. The strands in the 2nd and 3rd row need to be moved to the center. Thanks…

I have multiple runs of different substructures in stand alone OBD. I'd like to copy a few of these files to a new OBD file to condense and share with colleagues.

Hi, In the article below it mentions that the issue where "Distance from top of concrete deck to the neutral axis of the composite section at the plastic moment was incorrectly calculated." is fixed. However, I'm still running into this problem when…

When I try to place bearings, my bent cap's elevation drops. It does however place the pads at the bottom of the girders but then it stretches the bearing seats all the down with the bent cap. What is driving the bent cap to drop like that? The Feature…

I would like to place barrier rail off the deck and on a wingwall. The program wants me to put the rail on the deck. I cannot horizontally offset the rail off the deck either. Best I can do is have the rail at the edge of the deck (Approach Slab) but…

I always get this error after designing the columns in LeapBridge Concrete Substructure Module (RCPier). Any thoughts on how to fix this error?

Does RC Pier check shear friction in the pier cap (AASHTO 5.7.4)? I've looked in the output reports and didn't see reference to this spec section. I've also looked in the application help interface and couldn't find it. Note: my application version…

This is a long one, but it's been bugging me for a while and I strongly believe this needs to be improved. I have created a .cel to use as a functional component for a custom pier or custom abutment. This cell has 2 columns. I have placed this cell…
