hi all, I have a few questions as follows: 1. During the construction of cable-stayed bridges, does the Traveler of Main Girder stiffness model always have to be considered for cable-stayed bridges to increase the stiffness of Kn girders? 2. If…

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.

There does not appear to be a way to model a built-up plate girder diaphragm in OpenBridge (I have to place diaphragms between adjacent girders - I cannot skip a girder, and I cannot model a built-up section), or to model a substringer system. I see notes…

Hi everybody! I started working with OpenBridge Designer few weeks ago. I am still getting to know the software but I realised I need some guiding in producinig drawings. I finished modelling a segmental bridge without reinforcment, and I'm not very…

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…

Hi everybody. I am currently modeling a suspension bridge with a span diagram of 125m-400m-125m. And, I have referenced how to calculate tension of main cable and hanger cable as instructed in Demo of RM Bridge V8, and I obtained a deflection of 2…

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…

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…

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…

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.?

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…
