I am trying to model a bridge that has two abutments and five piers. I have two beam groups (one with 7 beams and the next with 8) that changes at the middle pier. At this point I need the deck to have a gap 20" wide, which is filled with a joint filler…

Hello all, I have had some issues with LEAP steel pulling reactions when using Line Girder or Grillage analysis. These are the Service I HL-93 support reactions when running a Line Girder analysis. I am wondering if this is a glitch in LEAP Steel…

When I transfer from OBM to LEAP Steel, the field splice display is not showing properly. Usually the display shows like the picture below with the plates and bolts. Instead it is showing up with nothing. I'm assuming it is just a glitch from…

Hi, When I send my physical model from OBM to LEAP Bridge Steel, I am getting following error message. "File Path is not valid". Please advise how to resolve this issue.

Hello, Does LEAP Steel check intermediate and bearing stiffeners? I've gone thru the design reports and didn't see the stiffeners were checked anywhere. Thank you!

I am designing a pedestrian bridge, so I deleted the Live Loads and added a pedestrian load that is applied to a sidewalk that covers the deck. The analysis runs for both line girder and grillage, but when I try to run the design check everything goes…

I can't find any place in LBS that asks for ADTT. So my conclusion would be that it is always using Fatigue I. However my ADTT is low enough that I should be using Fatigue II according to AASHTO 6.10.10.2, but I don't see anywhere that would tell LBS…

Are the support reactions reported for Live Load factored or unfactored? Can total reactions be reported per load combination rather than per load case?

Hello, I am working with a colleague to load rate a bridge for state loads but he is not able to see the truck configurations I've input into my model. I have searched for the vehicle library file to send to him so that he may add to his program files…

Good morning, After completing my superstructure design, I used the substructure design/analysis tab to import all of my loads from the superstructure into the substructure. It pushes all the data into .rcp format. Then, I try to create vessel impact…

The PGL of the bridge is a straight line followed by a horizontal curve. The curve portion starts at the middle of a span. Bridge deck is tapered for the straight line portion and constant for the curve portion. I tried the three different ways (Independent…

How do you get Leap Steel to print influence lines for a specific point on the bridge?

How does Leap Bridge Steel treat diaphragm end connections for FEM models? My analysis results only yield axial loading and all of my shears and moments have a value of zero, suggesting pinned ends are used within the software. This is in contrast to…

Is there a way within LEAP Bridge Steel to report analysis results for load combinations (Strength I, Service II, DC only results, etc.)? I have found where results are broken up into their service components under analysis reports, but I can't find a…

Hi, Dear Sir/Ma'am, I am studying LEAP bridge steel now. I notice that in the tutorial that we can see the roadway in a 3D manner. However, I am not able to do it with the LEAP bridge steel V20. Could you please teach me how to view the roadway in a…

In LEAP Bridge Steel, when defining the Pier/Abutment Locations, what exactly is the user defining when they input a station for an Abutment aka Support 1. Is it the centerline of bearing for the girders ? Or is it the centerline of the abutment stem…

I am modeling a bridge in LBS that has a 2.625" bituminous wearing surface; however, I do not see an option to include this information in the model. When I define the vertical curve, the model places the crown of the deck right on the profile grade line…

I have created AASHTO LRFD Strength III and Strength V load cases and defined wind loads; however, I do not see where these loads are reflected the output for the lateral flange stresses? What exactly are the capabilities of LBS with regards to lateral…

Open Bridge Designer Version: 10.08.01.30 Open Bridge Modeler Version: 10.08.01.87 Leap Bridge Steel Version: 20.00.00.24 I am having difficulties with using leap bridge steel within the open bridge designer application. I am finding that each…

Hi All, I'm calculating the screed elevations, top of haunch elevations, and final deck surface elevations. I had the following questions: Is there a way to get OpenBridge Modeler or LEAP Bridge Steel to provide these elevations? Or is the best…

I came across these issues while trying to export models from OBM to LBC and LBS. 1- When I send a skewed prestressed concrete bridge with the back of abutment as reference line to LBC, the transferred model will end up having flared beams and wrong…

Has anyone seen this issue in lasted version of LEAP End user has new Lenovo P52 laptop and all drivers up to date. When rotating object you get a fan image around object as shown in screenshot. We have another user with same P52 laptop and drivers…

Has anyone else seen this error? I am trying to link an OBM model to LEAP Bridge Steel for the first time. Any guidance on where to start looking would be helpful. Thanks, Justin

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

I am having a problem while running the grillage analyisis with LEAP STEEL. I have the following error: An error occured while extracting DeckLoad results! This error is not appearing when executing a LINE GIRDER analyisis or a FINITE ELEMENT…
