I need to change the stress limits for the bent cap from normal exposure (=0.19 sqrt(fc) <0.6ksi ) to severe exposure (=0.0948 sqrt (fc)<0.3ksi)

When running analysis with and without P-delta I noticed there is a substantial increase in the axial column force when P-delta is applied. At the node 1 the difference is about 300 kips. What could be a reason for such an increase? Any insight is appreciated…

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…

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, 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…

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…

I am working on the Bentley tutorials but I am confuse on how all of the Open Bridge Desiner connects to Open Bridge Modeler and Leap. do we need to start from OpenBridgeDesigner to have the Modeler and Leap work together. When I create in OpenBridge…

When checking Show P-delta Effects in the Analysis tab, are the values shown represent values with p-delta effect? For example, are the column/shaft moments magnified with p-delta factor in these load combinations (with a "C" on the end of the LC#)? If…

I'm working on a two-span prestressed PCEF bulb tee bridge for a state DOT in LEAP Bridge Concrete v19. I'm new to LEAP Bridge Concrete, but I've used other LEAP products. We're at the TS&L stage, and I'm trying to get the preliminary design of the superstructure…

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…

Hello, I was wondering what edition of AASHTO is LEAP Bridge Concrete v16.00.00.24 using? I was unable to find it in the software itself so if it's possible to describe to me how I can find this within the program as well I would appreciate it. Thanks…

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…

First of all; I have already updated the user's machine to the newest version of LEAP Bridge Concrete. I removed the older version and restarted before installing the newest version. The error occurs anytime the user tries to open an LBG file created…

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…
