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, I am modeling a balanced cantilever rail bridge. There is no macro or load type on Derailment load in the RM analyzer. I cannot find any writing or discussion regarding the Derailment Loads in RM bridge as well. I know that I can create manually…

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.?

Are there any notes on the update to LEAP Bridge Steel CONNECT Edition V18.00.00.31?

I am using Leap Bridge Concrete to design a skewed wall pier. After analyzing the pier, I noticed that for the braking force, that the sum of the forces in the z-direction at the top of the wall did not equal the sum of the forces in the z-direction at…

I am using CONSPAN in my design and have a couple of questions about the method in which the program performs calculations. Does CONSPAN design prestressed girders, at the interior supports, as reinforced concrete beams? According to AASHTO, LRFD 5.14…

We are using RM Bridge Advanced version V8i 08.11.28.02, we have started using wizard function to model and input and we encounter some errors during analysis. kindly refer to attached screenshot 1 & 2 and also attached herewith the model file for your…

How does LEAP Bridge Concrete calculate the reactions for DL-Comp. (DW)? I added up all the DW reactions and compared to a hand calc of utlities and overlay loads. The total DW is nearly 4 times greater than my hand calcs. I have 4 beam lines with 0.05…

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…

When calculating the top and bottom stresses at the transfer and bearings, does LEAP take into account the development length? It seems that the stresses its calculating at the bearings and the transfer are higher than what they should be. Does LEAP use…

I am using the LEAP Bridge Substructure module to design a pier for a continuous 4 span structure using HS20 LFD loads. In the AASHTO Standard Specifications, it gives you a few options for the loading. One is that you can use a lane load with one concentrated…

I have modeled the box girder curved bridge in RM advance. But i could get the deflection at cantilever portion of either end. I don't know how i attached the tcl files Regard Pardeep from CRRI,New Delhi

How exactly should the vertical component of LL surcharge on the footing be input? I have a 100 ft long footing (x dir) with a 9.75 ft heel (z dir). Per AASHTO, I'm using the equivalent of 2 ft of soil for the surcharge. There's 80 ft of clear roadway…

Hello, I'm designed a decked bulb tee and I notice that the composite section is the same as the beam section. The composite section should include the closure pours, but I can't seem to find a way to make this happen via the program or manual override…

LEAP or RMBridge or STAAD pro.

Does anyone have calculation verification for the live load auto-generation function in RC-PIER? Or has anyone else had problems verifying the LL output from RC-PIER?

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…

Hello, There appears to be a font compatibility issue. In the program LEAP GEOMATH V8i, it looks like you should be able to adjust the window in order to see the rest of the menu, however there is no option to move it. This issue is not resolved…

Dear friend, The library of girder section on Leap Bridge or Leap ConSpan is so limited (Super T girder for example). Are there any solution to expand this one; it is a so wonderful if we can down load the extended library file for these program. If…
