  • [RM Bridge] stiffness Traveller of Main Girder

    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…
  • Steel composite bridge

    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…
  • upward deflection of the continuous bridge structure

    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.
  • Two bridges connection

    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.
  • Discontinuous Girders, Substringers, and Girder-Floorbeam Systems

    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…
  • Producing drawings with maximum information

    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…
  • Preliminary Geometry Layout in OpenBridge Modeler

    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…
  • updating leap concrete model based on OBM updates, Stand alone workspace

    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…
  • allowed deflection of the bridge under the effect of live load

    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…

  • Transition Girder?

    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 openbridge. How do I do that? I need slab beams.

    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.
  • OpenBridge Modeler Training Video - Beam Layout (Framing Plan)

    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 upgrading to the newest version of OpenBridge Designer I do not have OpenBridge Modeler

    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…
  • OBM Segmental bridge deck on a looped alignment - chainage +0 deck placement

    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…
  • openbridge superelevation

    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…
