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 steel girder bridges combined with concrete decks (continuous span girder bridges). If the concrete deck is not in tension and the combination of internal forces according to the Service limit state is service.sup, then use the ReloadSup function…

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…

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 everyone, I am looking for the value of stresses loss in tendon (lost due to relaxation of prestressing steel, lost due to relaxation of prestressing steel,.....), Can someone tell me where is it? I'm using rm bridge v11, Pictures below are the…

Hello, Camber and deflections are reported at 10th points along the beam. I am modelling a longer span which will require more than 10 screed points. Is there a way to toggle the number of points? Or do I have to interpolate? Thanks,

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 designing a 2-span precast prestressed beam bridge in LEAP Bridge Concrete CONNECT Edition v17.00.01.01. The bearing dimensions along the pier cap are shown correctly in the following view under the 'Substructure' tab: However, when you click…

How to model the concrete box section varying width in Plan as shown below?

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…

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 am trying to model a twin 4-span continuous slab type bridge using the ABC Wizard. I was able to import the alignment and profile from GEOPAK. From there, I also found how to offset the bridges from the alignment. The model show the roadway being offset…

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…
