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.

How does RC Pier (LEAP SubStructure) account for skew when calculating the bearing reactions for the Auto Generated Live Loads. I can replicate the reactions when there is no skew, but I have issues when skew is applied. Any assistance on the matter would…

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 am using the Substructure module of LEAP Bridge Concrete. According to AASHTO LRFD, you can't have a truck on both the approach slab and on the deck, but you can have a lane load on both. When generating live loads for an abutment, there are two…

The depth of my Abutment Pile Cap displays correctly when shown in the "Edit Abutment" window but is not being shown correctly in my 3D model. It is currently shown being shown much deeper. I also have a few general comments/suggestions regarding…

Can LEAP RC-Pier analyze/design for a cantilever abutment? I used RC-Pier for Abutment Cap with Pile Design before, but not sure if it works with cantilever abutment design. Thanks Alex

Good morning all, I have several users that run LEAP Bridge Enterprise, but I do not run it myself, so my apologies if this is a dumb question. The little bit that I have seen when they are running it, the custom libraries are stored on each user's…

I need to model a cantilever. Please direct me to relevant links/files/resources

Is it possible to model a prestessed beam using two different sizes of strands. My top flange has 0.5" tendons pulled to 2000 lbs. However, the main reinforcing strands in the beam are 0.6" 270K LL. Is there any way to accurately model a cross section…

I am designing an adjacent box beam bridge with a variable depth deck in CONSPAN. I cannot figure out how to input a 4.5" deck thickness at the copings, and a 8.5" deck thickness at the structure centerline. Can someone please assist me with this task…

Is there any provision of defining median or divider in a bridge model in leap ?

Hi, I am trying to fix the lane position on a bridge which carries railway traffic. Does Leap have the option of fixing the lane width to certain value and certain position , as in a railway bridge the position of rails are fixed ?

My company recently updated to the latest version of the LEAP Bridge software, Version 16.00.00.24. I am designing a pier and have run into a problem in re-opening the design file later after exiting LEAP Bridge Concrete. I created the substructure…

LEAP or RMBridge or STAAD pro.

I am trying to model a twin 4-span continuous slab type bridge using the ABC Wizard. I was able to import the alignment and profile from GEOPAK. From there, I also found how to offset the bridges from the alignment. The model show the roadway being offset…

Hi, Dear All, Today when I open my LEAP Bridge CONNECT edition, this warning from CONNECTION client pops up. "Error Error #9149C044-35D6-4B99-B165-8334E6719C0B There was an error processing your request. Please try again later, or if you…

Does anyone have calculation verification for the live load auto-generation function in RC-PIER? Or has anyone else had problems verifying the LL output from RC-PIER?
