Hi all. Can you tell me what the allowable deflection of a suspension bridge is? And what standard is this deflection limit based on? best regards.

Hi all. In composite steel girder bridges with concrete decks (continuous span bridges), does RM bridge automatically Calculator effective width of deck to calculate short-term and long-term composite cross-sections? best regards.

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 wondering how LEAP Version 21.01.00.22 calculates the maximum axial load displayed in the diagram. The diagram displays a maximum axial force allowed of 1802 kips. As expected the 1802 kips doesn't change regardless of the load combination…

I am performing a load rating of concrete box girders. The rating factors/tons is not displayed since the Inventory Design Load Rating Factor > 1. Is there an option to make the program display the factors even if the RF is greater than 1 or is that information…

Hello again, I have other question, I tried to conect OP model with RM Bridge but the program send me an error, I don't know how can I fix it Do you know how to fix the error E0053? or give an idea of what this Error E0053 wants to tell me

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…

Dear All, I am trying to perform QAQC for a substructure-only model and have a couple questions. (LEAP Bridge Concrete stand-alone program) Checking Live Load Generation: Where can I find the output for the live load distribution factors that were…

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…

Hi all. I have a question about Reinf crack for prestressed concrete as follows: If you calculator stress bot of section beam in MinMz_Service exceeding allowable stress tension limit is 0,5 x sqrt(f'c), you can calculator reinf area to control crack…

Can anybody please tell me how to investigate Whether the External tendon Profile is interrupted by each other? - in the picture above I try to set tendon profile across each other, But no any "Warning" or "Error" showing after I run my model Tha…

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…
