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…

Does RC Pier check shear friction in the pier cap (AASHTO 5.7.4)? I've looked in the output reports and didn't see reference to this spec section. I've also looked in the application help interface and couldn't find it. Note: my application version…

Hello, I have 95 ft long and 12 ft wide abutment footing on 2 rows of piles. Abut stem is 88 ft long. How is the Leap program calculating Dist (ft) , dv, Vu and Phi Vc for X and Z ? I will appreciate the response. Thanks,

Hello, This is an issue that I have seen with previous versions and still has not been resolved. When the need for different material properties and other design parameters is different from the generalized materials tab parameters, the use of the…

Hello, After the update to OBD and possibly to Leap Bridge I noticed that multiple saved strand patterns and shear reinforcement layouts in the leap model from the previous version have been completely erased when reopening the same model with V10.10…

Hello, While analyzing and designing a continuous structure, there is an option for negative moment continuity steel. As outlined in the Tutorial PDF T1A-5 (pg. 47), we input the continuity steel but when looking at the strand patter design status,…

Hello, Is LEAP Bridge concrete / RC-Pier capable of having a structure simple span for dead load and continuous for live load (SDCL)? Thanks.

How does LEAP Conspan apply multiple presence factors if live load distribution factors are entered manually? If distribution factors are entered manually, is it up to the user to apply the multiple presence factor to the manually inputted distribution…

Hi, all I have generated the model for 2-span, continuous span model. The negative moment reinforced rebar is supposed to be taken care of the negative moment. I have input the negative rebar but it seems in the strand pattern check, the program assumed…

When opening from OBD Connect Edition, I accidentally double clicked on the Leap Bridge Concrete button, and it tried to open up 2 instances of the file. It generated an error, I don't remember which one, and now it won't open my file. I'm afraid I lost…

PDF When designing the end bent of a bridge unit (continuous unit), how do you get leap concrete to read the live load cases from the previous unit? The program only models one bearing line and doesn't seem to have an option for import of the loads…

Hi, I am trying to design prestressed concrete 78" Girder with 8.25" Slab thick. my Prestressing steel centroid is Ypg=9.88 in and total section height H=86.25" so my dp=H- ypg=86.25-9.88=76.37". I have no mild reinforcement in the girder, so dp=de…

I am creating a custom I Beam section but the input fields are constantly being locked, preventing me from updating the dimensions. Restarting the application and going straight to the Beam Section Library sometimes, but not always let me update the dimensions…

Hello, I am designing the shear reinforcement in a straight pier cap for a multi-column pier. The issue I am having is that whenever I increase the number of legs for my stirrups, the area of steel required also increases to the point where increasing…

Hello, I have a problem in the beam section analysis. I assigned rebars to the beam but the program says I have "0 Ast_prvd" at the transfer location and I want to know if there is any way to fix this or if there is a special setting I should look for…
