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.

Hello, I,m trying to create a Bent where 2 separate bridges meet, is this even possible to model in Openbridge Modeler? Ultimately, I want to transfer the model to LEAP to run the analysis.

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…

I am having to change some geometry and beams deck, spacing Pedal stools and so on. I had already exported from OBM to Leap but need to update that Leap model to reflect the new changes done in the geometry. How do I Update that Leap File without having…

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…

I have a bridge that has a irregular deck due to a ramp entering onto the bridge. Because the deck is wider at the ramp entrance we have added an extra beam in this area. This extra beam does not reach a full span from support line to support line. Instead…

I need to create a new beam type in open bridge. there are two different sizes. one is 12" tall X 3'-11.75" long and the other one is 12" tall x 4'-11.75". In Texas they are called slab beams, but I am not sure how to create two new ones.

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…

After using Connection Client to upgrade to the latest version of OpenBridge Designer, upon completion I do not have the program OpenBridge Modeler. The Leap products are there but no OpenBridge Modeler. Has this happened to anyone else? During the install…

I'm modelling a segmental viaduct on a looped alignment. Using the Place Cantilever Segmental tool, I'm finding that the span which is over the start/end chainage of the alignment, OBM won't model the deck (screenshot attached). Is there a trick to modelling…

Hi, I am new to OpenBridge Modeler. Can anyone advise whether can create a superelevation directly or purely based on the plane alignment line? I attached my sample , I couldn't get any item display via the superelevation editor, maybe something not…

While trying to update a variable constraint on a deck I get this message: Cannot access a disposed object. Object name: PropertyGridView.

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 ?

Hi, I'm modelling a conceptual bridge which will be standing on floating pontoons tethered to the sea bed. The tethers I created using a pier template, utilising a steel column as my tether. This is elevation constrained to the pontoon and the terrain…

Hi, actually im working on a CONCRETE bridge with I-Beams in the program OpenBridge Modeler and I cant find an option to model the diaphragm beams. I wonder if is it possible or I have to model this in other program?

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…
