I am using OpenBridge Modeler CONNECT Version 10.07.00.50 to make a test model of a bridge that we are currently working on. It's mostly a proof of concept but I am running into a few issues while modeling. The primary issue being that with the relatively…

Where could I find the link to download the Leap steel bridge modeling software? Thanks.

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 could not find any documentation regarding the "Sectionize" button within the Member Shape Description in LARS. What is the function of this button? Is it related to saving prestressed strand patterns? Is this possible in LARs? Thank you, …

Hi All, Can I do a bridge composed of reinforced concrete precast beam channels in Leap Bridge Concrete? None of these beams are prestressed on post-tensioned, so I want Leap Bridge to check it simply as reinforced concrete with steel rebar.

I am currently trying to edit a bridge previously created in open bridge I receive either an error stating cannot edit constraints of non-active bridge or unit or on other occasions I receive an error stating "cannot update the bridge in this model. Please…

Hello, I have a trouble with a variable thickness of deck throughout the span of the bridge. I was using template for a deck slab w/ constraints and then I was trying to define the variable thickness by using variable constraints. At the preview it looks…

Hello, Camber and deflections are reported at 10th points along the beam. I am modelling a longer span which will require more than 10 screed points. Is there a way to toggle the number of points? Or do I have to interpolate? Thanks,

Are there any notes on the update to LEAP Bridge Steel CONNECT Edition V18.00.00.31?

My situation is that I have an alignment sent to me as an alg file, which I have imported into OpenBridge and have used to make bridges. I have received another alg file which contains updates to the current alignment. Whenever I try to import this new…

Hi all, I am a civil engineer student and I'm working on my final year year project. The project is a curved composite bridge (Steel box and concrete slab). I'm currently facing a problem with the axis which is 200 meter long and 38.1m of radius.…

When I generate live loads I do want the program to include the two design truck load for live load reactions but it does not seem correct to use that load when calculating braking forces. They should only be based on the design truck per AASHTO LRFD…

I am using Leap Bridge Concrete to design a skewed wall pier. After analyzing the pier, I noticed that for the braking force, that the sum of the forces in the z-direction at the top of the wall did not equal the sum of the forces in the z-direction at…

I am designing a 2-span precast prestressed beam bridge in LEAP Bridge Concrete CONNECT Edition v17.00.01.01. The bearing dimensions along the pier cap are shown correctly in the following view under the 'Substructure' tab: However, when you click…

How to model the concrete box section varying width in Plan as shown below?

How does LEAP Bridge Concrete calculate the reactions for DL-Comp. (DW)? I added up all the DW reactions and compared to a hand calc of utlities and overlay loads. The total DW is nearly 4 times greater than my hand calcs. I have 4 beam lines with 0.05…

In the Shear/Moment Envelope (&Reactions) Design output what is the difference between live load Max, Truck, and Lane? Is the max HL-93 including truck and lane loading? I have a 6 span continuous concrete superstructure.

Dear All, I am using RM Bridge for CFD to compare values with wind tunnel test. I am able to do cfd for predefined deck section but when I make my own deck section, In Analyzer --> Aero classes when i try to do the CFD error message displays ""Cross…

Hello, I have been trying to prepare model with FEM element for composite bridge. After I lot of failed trials and errors in my model I have tried to model one training example (Composite-basic-E-EC) using FEM. But also had a lot of errors. https…

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 try to create a pier with a tapered cap, which is unsymmetrical and with a column near one edge. Is it possible? I know i can create a symmetrical cap with a column offset from the center, but the location of non-tapered segment cannot be modified…

Hi All I'm using preprocessor for Cable Stayed Bridge for modeling cable sagging: in step 2 (6.6.5.3 at U.Guide): "Per-forming the analysis with this totally restrained system and the option Cable sagging selected will give the sagging line of all…

I am trying to model a twin 4-span continuous slab type bridge using the ABC Wizard. I was able to import the alignment and profile from GEOPAK. From there, I also found how to offset the bridges from the alignment. The model show the roadway being offset…
