Hello - I am modeling hammerhead piers in RC-Pier Version 20.00.00.58. EQ/ES/LS loads are applied at the bottom of the column with a user-defined seismic load combination. For some piers, the seismic shear output at the top of the column shows Combo …

Has anyone else had this issue? I can run an analysis and nothing gets flagged in the "Under Design Report", but after looking at the Strength V Limit State reports there are failing members in Shear. Also I have attached an example picture of what the…

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…

Hello. My pedestrian Load is 90 psf. My bridge width is 16ft. I am trying to apply 1440 plf load as pedestrian load and its a simply supported girder. Span length is 130 ft. Based on hand calc the moment in the center is 3042 kip ft. But the load shown…

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 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…

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…

I am currently design 4 bridges in LEAP Steel v19 but am encountering an issue with the tool to automatically generate loads for the wearing surface of the structure. The bridges are all of a similar type, but some are wider than others and one is on…

Hi, I've encountered a scenario in prestressing design where with the decreasing of total number of strands, the Mu provided somehow increases. Attached are two screenshots with different total number of strands & corresponding Mu. -Total number of…

Hi All, I'm calculating the screed elevations, top of haunch elevations, and final deck surface elevations. I had the following questions: Is there a way to get OpenBridge Modeler or LEAP Bridge Steel to provide these elevations? Or is the best…

When using the "Generate Default Load Combination" feature, the load combinations generated are using different factors, like : - 1.4 for WS for STR GP 3, - 0.4 for STR GP 5, - and 0.3 for SER GP 1. LRFD 8 specifies 1.0 factor for all WS regardless…

I am using Leap Concrete Version 18.02.02.03 for a multi column pier design that includes seismic forces. I need to apply a response modification factor for the columns and the help guide states that this can be modified in the Seismic Parameters. However…

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 ?

What is the difference between the stresses given for the depression point in the "Release Stresses" box and the "Release Lifting Loops" box?

Hi, I'm using LEAP Bridge connect edition. Is there a way to get combined dead load deflection ordinates from LEAP bridge? I know the camber table will provide these values, but we prefer to also have a more formal table of values for backup design…

I hope this is an easy question regarding the shear stirrup spacing... Does the program insert a stirrup at the start location specified? For example, in the image below, is there a #3 2-legged stirrup provided at 0.00', 0.25', etc. or do the stirrups…

Is there a way to add a supplemental composite DW load for a poly wearing surface in Leap Concrete Bridge? I want to keep it separate from the Future Wearing Surface (Composite DW) load I already have. This is necessary to accurately calculate camber…

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…

In Conbox, when we select the Self weight reaction in the analysis model, does it include the self weight of the piers defined as well?

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.
