How to create a standalone Substructure or Superstructure only model in OBD?
Below are the steps to create a Substructure or Superstructure model:
Open OBD and open your OBDX file
As shown in the screenshot below:
Choose the Standalone workflow; by selecting Standalone, not the Default BIM Workflow, at the top right of…
OBM Create Substructure Drawings Cut Plane Orientation
I'm using the built-in workflow for creating substructure drawings as seen here. When I click on the pier the automatic section plane is shown at an angle, not parallel to the Support Line. The angle appears to be random, not associated with global coordinates…
Can you model a curved or bent supportline in OpenBridge Modeler?
Wondering if there is a way to model a curved or bent (broken-back) support line in OpenBridge Modeler?
Thanks,

Distances in the Pile Layout
In OpenBridge Modeler the distances in the Pile Layout Tab can be manually edited to update the model individually with the pile's on-site construction errors. Local eccentricities can be added to the model by modifying the current pile Distances.

OpenBridge - GenerativeComponents - GCP file - Place Custom Pier
Hello Everyone,
I would like to use GC in our modeling in OBM in modeling bridge supports because in FC (FunctionalComponents) I encountered some limitations . From what I understood, I should prepare the entire geometry with variables in a separate…
OBM: Tapered or Variable Cap
OpenBridge Modeler has many very functional options in the Substructure Template , specifically for the bent Cap, we currently have four possibilities to model it directly from the Library:
Tapered : the tapers of the pier cap are narrowing at its…
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?
LEAP Bridge Concrete Substructure Auto-Design
Hi, Dear All,
Please see the following picture.
Questions:
1. Is it possible for us to look into the footing design calculation details in LEAP bridge substructure?
2. The required bar area is constant through the footing for both X & Z directions…
Questions about Wind Load Generator and some more in Leap Bridge Substructure
Hi, Dear All,
Could you please let me know how the Z is calculated in the wind load generator?
How do we deal with the wind load on the crush wall which is under the column but above the footing?
Also, what is the best practice to enter the buoyancy…
16. Friction Pendulum System - Seismic Isolation - High Load Multi-Rotational Bearings
For RM Bridge inside OpenBridge Designer , as shown in the pictures below, the Friction Pendulum System - FPS - is a support device that provides the structure with some level of Seismic Isolation , it is also known as High Load Multi-Rotational - HLMR…
How to save reinforcement design? LEAP Concrete Substructure
Hello,
I am working in OpenBridge (10.9.1.15) StandAlone LEAP Concrete. I have a question about how to save reinforcement design in LEAP Concrete. When I am working in Substructure, I generate loads, run analysis and then design the reinforcement…
Inverted T Beam- Ledge Reinforcement
Hello,
How do I control the spacing of the ledge reinforcement for an inverted T beam? I do not see a dialog box, I'm using LEAPBridge Concrete V 21.00.00.24.
Thanks,
Circular reinforcement pattern on Square Column
Hi
I am looking to design a square column on a drilled shaft/Caisson however the square column size is larger than the caisson and would like to introduce a circular longitudinal reinforcement pattern in the column, so it sits well into the drilled…
Partial Twin Leaf Pier Connections
The Partial Twin Leaf Pier Bottom Connections could be modeled by attaching the Previous full Cross-section to the new Double Leaf CS thru its nodes.
As shown in the picture below, the best practice is to use different node numbers and use rigid links…
9. Flexibility & Stiffness Matrix
The Demo Example number 9. Flexibility & Stiffness Matrix has an example of how to group elements to represent their structural behavior.
In general, it is very useful for large projects to reduce the size of the model and therefore the computational…
Custom Load Group and load combination (wind load)
![Dilip Matange [Bentley]](https://communities.bentley.com/cfs-filesystemfile/__key/communityserver-components-imagefileviewer/system-images/anonymous.gif_2D00_44x44x2.png?_=638052675279785313)
When we use new/custom load groups the program is not generating Load Combinations for the respective Wind loads as it does when using default load groups. It seems to be generating as if we were using the cross combination option.
Current LEAP Bridge…
How to access RCPIER in LEAP
To access RC-PIER in LEAP users just need to select the Substructure Tab in the Project and hit the Substructure button, as indicated by the red arrows in the screenshot below.
Pier View Direction
Substructure allows users to define a pier looking at it in an upstation view or in a downstation view. This affects the way cap/column/footing geometry and loads are defined.
When pier is defined in upstation view, it is defined looking at the…
How to reduce Load Combination processing time?
The Load Combination and Analysis is a very memory intensive process. If you have too many loads you should try reduce them so that # of generated loads is less and in turn the analysis will run better. Here are some steps that may help.
One of the…
Column Spring Supports
By default columns are fixed at bottom. However, program allows users to specify a spring matrix at the bottom of every column if partial fixity is desired. Program provides two options for this. First option allows to define diagonal entries in the spring…
How is bearing pressure/soil pressure calculated for isolated spread footings?
QUESTION: How is bearing pressure/soil pressure calculated for isolated spread footings?
ANSWER: For isolated spread footings, forces and moments obtained from each load combination, at the top of the footing, are applied at the centroid of the footing…
