Hello, I've been having issues with Leap Bridge Concrete with the flexural capacity. It seems like the program doesn't think the bars are fully developed when checking the flexural capacity at the exterior girder location (see image below) Though…

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.

Hi all. Can you tell me what the allowable deflection of a suspension bridge is? And what standard is this deflection limit based on? best regards.

Hi all. In composite steel girder bridges with concrete decks (continuous span bridges), does RM bridge automatically Calculator effective width of deck to calculate short-term and long-term composite cross-sections? best regards.

Hi all. I hava some question about steel composite brige as follows: 1. To calculator stress point of section, Rm Bridge automatic use short-term section for live load and load case type Non-permanent and use long-term section for load case type Permanent…

Hi all. In continuous beam structures, the allowable downward deflection of the bridge under HL93 load is L/800. So may I ask what is the upward deflection of the continuous bridge structure under HL93 load? best regards.

I created a bridge in OBM that is associated with a placeholder "Alignment A", which I created in my OBM model. Roadway has since provided me an official "Alignment B" for the project which I have referenced into my OBM file. Is there a way to associate…

Hello GC Community. Lately we are testing possibilities of OpenBride Modeler and GenerativeComponents to see if it is possible to implement them into our company and optimize current workflow. During test we encountered some issues which we do not fully…

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

Hi Experts, I have just updated to latest version of OBM (2022 R1), I have tried to explore Itemtypes and have few questions, 1. Is Itemtype library assigned to feature definition by default? (Eg. If I place a deck and have feature definitation…

I am trying to re-run an old '.BMD' LARS file that was created in version 5 back in 2013. I installed version 20.02.00.101 and followed the instructions to convert the '.BMD' file to a '.LRS' file. When I open the new '.LRS' file on one computer,…

Hello, I am Ranjit from Sagar Steel Corporation I've seen some videos that show Itemtype is attached to elements that can report a lot of element properties within OpenBridge, and I've read the wiki on this page that itemtype information cannot be transferred…

Hello. I'm wondering how LEAP Version 21.01.00.22 calculates the maximum axial load displayed in the diagram. The diagram displays a maximum axial force allowed of 1802 kips. As expected the 1802 kips doesn't change regardless of the load combination…

I am performing a load rating of concrete box girders. The rating factors/tons is not displayed since the Inventory Design Load Rating Factor > 1. Is there an option to make the program display the factors even if the RF is greater than 1 or is that information…

Hello again, I have other question, I tried to conect OP model with RM Bridge but the program send me an error, I don't know how can I fix it Do you know how to fix the error E0053? or give an idea of what this Error E0053 wants to tell me

使用OBM创建“阶段施工桥梁”时，无法创建“挂梁”，这个问题该如何解决？

I made a video of how I used OBM to optimize span layouts, check vertical clearances, check clash detections, etc during the pursuit phase of a project. Being able to do these things in OBM led to us winning the project so I thought it would be worth…

Hello, We need to model the following columns but the templates only give the option to model circular, rectangular (chamfer, fillet or bevel) and oval, with no option to include these aesthetics elements in the corners of the column. Would it be…

Dear All, I am trying to perform QAQC for a substructure-only model and have a couple questions. (LEAP Bridge Concrete stand-alone program) Checking Live Load Generation: Where can I find the output for the live load distribution factors that were…

Hi all. Nice to meet you. I have a model steel composite cable-stayed bridge with 6 span continuos by Rm Bridge V8, 2 side span have 150m, 4 main span is 300m. I don't known about allowed deflection of the bridge. I use AASHTO LRFD standard. If you…

Hi all. I have a question about Reinf crack for prestressed concrete as follows: If you calculator stress bot of section beam in MinMz_Service exceeding allowable stress tension limit is 0,5 x sqrt(f'c), you can calculator reinf area to control crack…

Can anybody please tell me how to investigate Whether the External tendon Profile is interrupted by each other? - in the picture above I try to set tendon profile across each other, But no any "Warning" or "Error" showing after I run my model Tha…

So I have been thinking about this for a while now and wanted to get others input an opinions on the best way to model a very wide bridge in OBM. I have a very simplified model of the bridge which I created with ORD but would like to migrate the model…

New video up on my channel giving an in depth look at how to layout beams in OpenBridge Modeler, link below. I cover straight (chorded) prestressed concrete girders as well as curved steel I-girders. Definitely a few things that will save you a lot of…
