Bar Development Error for Calculating Flexural Capacity
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…
Main Screen Model & Diagrams
In RM Bridge one of the fastest ways to check results and display the model is directly at the Main Screen. It's easy and fast because any additions or necessary modifications can be made directly at the screen menus.

Concrete with time effects (C&S) creep and shrinkage
The time dependency of specific material properties can be considered in the OpenBridge Designer analysis. In RM Bridge , these time dependencies are defined by variables for creep, shrinkage, and relaxation which are definitions prepared for each material…
Leap bridge concrete Flexure check
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.
Non-linear stay cables sag
There are multiple options to consider Cable Sagging in RM Bridge , the user choice should be related to the model needs according to the problem relevance, namely its size and complexity.
Initially, the Elements Type Cable is used to have Normal tension…

allowable deflection of a suspension bridge
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.
short-term and long-term composite cross-section
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.
Steel composite bridge
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…
upward deflection of the continuous bridge structure
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.
[OBM] How can I change which alignment my bridge is associated with?
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…

GenerativeComponents & OpenBridgeModeler several general and lesser questions
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…
Post Tension Straddle Bent Design
Is it possible to design post tensioned straddle bents in OpenBridgeDesigner/LeapConcrete? If so is there any tutorials on how to perform the design?

Define Itemtype by feature definition
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…
LARS Display Issue
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,…
Itemtype export in OpenBridge Modeler
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…
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…
Circular Column Interaction Diagram
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…
