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…

In Leap Bridge Steel, I have a curved bridge, so the girder lengths are not integer values. Under the Member Definition tab I'm unable to manually input flange plate lengths to a sufficient decimal in order to be able to run analysis (see below for the…

Hi, In the article below it mentions that the issue where "Distance from top of concrete deck to the neutral axis of the composite section at the plastic moment was incorrectly calculated." is fixed. However, I'm still running into this problem when…

I need some advice. Situation I have a flared steel bridge. the bridge is continuous. i am using leap steel bridge. there are 6 girders. basically girder spacing at abutment 1 is 14 ft +/- and pier 2 is 13 ft +/-. (Flare portion). From Pier 2…

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,

I am seeing different minimum moments in my pier cap when comparing the cap design output and moment diagram to the actual analysis output. The cap design and moment diagram are both reporting a maximum negative moment of -3599 k-ft, but the analysis…

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 I transfer from OBM to LEAP Steel, the field splice display is not showing properly. Usually the display shows like the picture below with the plates and bolts. Instead it is showing up with nothing. I'm assuming it is just a glitch from…

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 having to change some geometry and beams deck, spacing Pedal stools and so on. I had already exported from OBM to Leap but need to update that Leap model to reflect the new changes done in the geometry. How do I Update that Leap File without having…

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…
