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 we try to copy the beam sections (BT-54) without changing any properties, the strands layout is disturbed and few of the rows are disappearing. Original Girder section strand arrangement Name Changed Girder Section strand arrangement Top…

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?

I'm working on a two-span prestressed PCEF bulb tee bridge for a state DOT in LEAP Bridge Concrete v19. I'm new to LEAP Bridge Concrete, but I've used other LEAP products. We're at the TS&L stage, and I'm trying to get the preliminary design of the superstructure…

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…

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 ?

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…

I have created a Leap Bridge Enterprise file consisting of a 3 span precast girder Conspan Model, and single column bents with bent caps created in RC-Pier. I'm trying to generate WS loads from the Auto Generate feature. I assume the Wind Pressure for…
