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 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…

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…

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…

How do I calculate AX, IX, IY, IZ, AY, AZ, YD, and ZD for a T-BEAM bridge section in the general option in STAAD ?

I can not load my Explorer dialog box or my Properties dialog box. When I try I get the following error message: Loader: Could not load application C:\Users\brownj2\AppData\Local\Temp\Bentley\OpenBridgeModeler\10.0.0_1\AddInLoader1.0\Bentley.ECUISupport…

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…

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

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.?

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…

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…

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…

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…
