Hello, I've been having issues with Leap Bridge Concrete with the flexural capacity. It seems like the program doesn't think the bars are fully developed when checking the flexural capacity at the exterior girder location (see image below) Though…

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…

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 ?

I am using OpenBridge Modeler CONNECT Version 10.07.00.50 to make a test model of a bridge that we are currently working on. It's mostly a proof of concept but I am running into a few issues while modeling. The primary issue being that with the relatively…

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…

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…

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 supporter, I study to use Leap Conspan with I section girder; normally, the cross section of this type of girder has the difference from middle and end position (end cross section is bigger than middle one). I could not found any function to describe…

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…

Dear Sir, Am a young engg. and new to staad pro. I just have to calculate an approximate moment calculation for moving loads for defined. Just for study purpose. i have created 2 beams and a set of loads defined for loading. i have generated load…

I am designing a two stage pier wall. There is no option for just a wall in RC pier. Is there a way to trick the program, I have tried a couple of different options but none have worked. The top wall is tapered in both directions and the bottom wall does…

With the release of LEAP Bridge Enterprise SS5 v12.01.00.57, we are eager to get all of our LEAP product users onto the latest and greatest, however our environment is currently a mixture of LEAP Bridge Precast 9 and 10. Is there any supported upgrade…
