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…

Hello there. In OpenBridge CE-Version 10.11,the following item is attached with the beam. However,after placing bearing，the beam item attached is missing. This problem will not happen in lower version software. Can it be fixed? Thanks.

Hi. When LEAP determines the moment interaction diagram of a column that was analyzed using P-Delta affects does LEAP adjust the moment interaction diagram for the deflections? Such as for a loss of stiffness in the columns due to the deflections as stated…

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.

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…

I'm running a curved bridge in LEAP Concrete. The begin and end bents have different skews resulting in variable girder lengths. LEAP suggests running the, "Girder-by-Girder" analysis. However, when running this analysis my girder is failing, miserably…

I am designing a hammerhead pier using the substructure module in LEAP Bridge Concrete. The geometry is a little odd...it's a hammerhead cap on a circular column. To compare the results for the cap design from the conventional sectional design & strut…

When I generate live loads I do want the program to include the two design truck load for live load reactions but it does not seem correct to use that load when calculating braking forces. They should only be based on the design truck per AASHTO LRFD…

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 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.

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 try to create a pier with a tapered cap, which is unsymmetrical and with a column near one edge. Is it possible? I know i can create a symmetrical cap with a column offset from the center, but the location of non-tapered segment cannot be modified…
