Hello, I need to run a flared girder analysis with two different beam types on the same span. I have been able to do this for a while without any issues, but now any new model I make with different beam types will give me an error when I re-open it…

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.

Some state DOTs require x/box beams without CIP concrete deck to be post-tensioned, as illustrated by the image below. The post-tensioned check box in LEAP Bridge Concrete becomes inactive when X-Beam/Box Beam is selected as the beam type. How do I get…

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?

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…

When calculating the top and bottom stresses at the transfer and bearings, does LEAP take into account the development length? It seems that the stresses its calculating at the bearings and the transfer are higher than what they should be. Does LEAP use…

Hello, I'm designed a decked bulb tee and I notice that the composite section is the same as the beam section. The composite section should include the closure pours, but I can't seem to find a way to make this happen via the program or manual override…

In the hand calculations tutorial for elastic gains HC-37 None of the gains listed in my output can be matched when using the equation above. Has the equation changed recently and the tutorial not updated?

From what I understand Conspan calculates 10th point increments from the total precast length and not the bearing to bearing span length. Is there a way to get camber and deflection readouts at the bearing to bearing 10th points? All the DOTs in New England…

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…

In the GEOMETRY tab in Conspan the dimensions for the various views (cross section, plan ,elevation) are very tiny and cannot be read. Is there a preference setting to make this dimension text larger? Or another way? Thanks.

Hi, I'm wondering if CONSPAN considers 90% the truck load when running double truck as per AASHTO LRFD 3.6.1.3 for negative moments or does it take the full truck loads? AASHTO 3.6.1.3: "For negative moment between points of contraflexure under…
