Hi If we define bar length, is leap bridge software have capability to deduct development length based on dia of bar and calculate flexure check at that point.

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 get the -nan(ind) error during final stress check whenever I provide temperature load for the girders. Is there a solution to this issue? I am using LEAP Bridge Concrete CE 19.02.00.33.

I don’t know when I use “include beam and slab contribution in Vu” and “Exclude Beam and Slab contribution form Vu” why are V vh-rg values zero?

Occasionally when I print beam design results, I will get zero camber and deflection values reported in the design summary. I have to go back and rerun the analysis and that clears it up. Is this bug documented and is there a fix?

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

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…

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.

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 ?

I have a single span bridge using I-girders that I need close to the max amount of strands in. These are all straight strands, and I've had to debond to 4 different lengths from the end. The longest debond is 25' of my ~90' girder. When I look at the…

Is there any way to get a customized output in CONSPAN or LEAP Bridge? For example if I only want to print stresses at the same 4-5 locations along with some other outputs. Is there any way to accomplish this?

Dear supporter, I study to use Leap Conspan with I section girder; normally, the cross section of this type of girder has the difference from middle and end position (end cross section is bigger than middle one). I could not found any function to describe…

What Time-Dependent Loss model does Conspan use (CEB 90, ACI 209, LRFD 6th etc.)? In the Design Parameters box in the Girder or Analysis tab there are options for Approximate Method, Refined Method, or Pre '2005 Interims' LRFD to compute losses. This…

I'm modeling a PC/PS Girder Bridhge in LeapBridge, Conspan and RC-pier, based on California amendments to AASHTO. I am able to import my Vehicular LL and Fatigue LL from CONspan into RCpier, but RC-pier isnt letting me import the Permit Loads. Do you…

Can someone explain to me why in Leap Bridge Conspan, when you hit auto design, it incorrectly designs the beam? It shows you rules/constraints that it violates. Why is that? Is there a way to fix that so it will design the beam correctly. Thank you.

Release 9.0.0 of the LEAP Bridge Suite is scheduled to be released June 25, 2009. Several outstanding features are included in this release. Here is a brief list of some of the new features for this version : LEAP Bridge v 9.0.0 incorporates the…

LEAP Bridge v8.1.0 incorporates the following enhancements: • The ABC Wizard can now directly read in alignment, cross-section and profile information from LandXML files. The bridge model can now be generated very accurately directly utilizing…
