As shown in the image above, I am getting extremely large spikes in the shear reactions at the bearings for my 3 span curved girder design. The smaller values along the bearings are the shear reactions I would expect to see. I only have slab loads selected…

How does one set up a deck slab template when the profile is not located at the alignment? In my case the cross-sectional shape of the deck is shaped like a simple gable roof but the grade line is not located at the peak (where the alignment is) but rather…

Hi Experts, I am new to OBM, I have done a few tutorials from online learning material. I wanted to know if OBM is the solution to Bridge modeling? Could you do the full detailed design of the bridge including all the components? (eg. On-Structure…

If I import an alignment from a GPK file into open bridge modeler civil accudraw does not seem to lock on to correct stations. No matter what I have the beginning station set to, OpenBridge seems to just start it at zero. I can use the civil analysis…

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…

Hi OpenBridge Community, Has any body modeled any Integral or simi-Integral bridges in OpenBridge Modeler? Has any body come up with a method for producing a 'down stand' as shown below? Thanks Oliver

Why is my abutment not full length in relation with the deck?

I recently upgraded to OBM SS3 (from 08.11.11.72), which appears to have lost all the library templates I created previously. Is there any way to retrieve my old decks, abutments, piers, etc.?

Hi, I have a question concerning the inserting point (WP) of a pier. As far as i can see, it's only possible to insert the pier directly under the main alignment. I'm missing the possibility to offset the inserting point. In my current project I…

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 a quantities report in OpenBridge the barrier quantity is way off. Any idea of how/where to look to fix this. The quantity should be around 380 LF but it's giving me about 906 instead.

How do I modify the beam template to have skewed ends as detailed by TxDOT for skewed bridges? Currently, the beam ends interfere with the abutment backwalls. ftp.dot.state.tx.us/.../igebsts1.pdf We do not want to put the beams on a skew but rathre…

How do I fix this problem and why did I get this?

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…

I'm currently running version 08.11.10.42 of Open Bridge Modeler. When anyone tries to cut a cross section using the following tool, the program crashes repeatedly. Has anyone else had this issue with this version? When is the newest version of OBM being…

This is my first time posting here so if this is the incorrect place for this type of post please point me in the right direction. I am trying to add a variable constraint to a deck template and am having issues. I seem to be able to control the Start…

The depth of my Abutment Pile Cap displays correctly when shown in the "Edit Abutment" window but is not being shown correctly in my 3D model. It is currently shown being shown much deeper. I also have a few general comments/suggestions regarding…

I am designing a hammerhead pier cap using the strut and tie method. RC Pier gives me main reinforcement using auto design but no shear reinforcement (stirrups). I can manually enter the shear reinforcement and it appears in the view but it doesn't appear…

LEAP or RMBridge or STAAD pro.

I have a single span bridge using I-girders that I need close to the max amount of strands in. These are all straight strands, and I've had to debond to 4 different lengths from the end. The longest debond is 25' of my ~90' girder. When I look at the…

Hello all: I am having an extremely difficult time getting through my bridge design on LEAP bridge. Especially while working in GEOMATH and RC PIER. In GEOMATH: Problem #1: Back when I was trying to make minor adjustments to the geometry of the…

I am making Drawing Levels for a couple of the DOTs we work with. We have multiple users on different machines. Is there a way to copy some files from my machine to the others so they will have these Drawing Levels set up already? If so, which ones? Thanks…

I am using Bridge Modeler/LARS (Release 4.00.03.00) to load rate a truss. In a previous model, the output included a table of concurrent forces but now I am not getting that table. Has anyone else experienced this problem? Larry
