LEAP Conbox/Bridge Connect Concrete : Shear Calculation
LEAP Conbox/Bridge Connect Concrete : How is the area of steel (Av/S reqd)required to resist vertical shear (Vs) calculated in the Detailed Shear Report when no stirrups are provided in a PT Box Girder design?
What’s New in the LEAP Bridge Concrete Patch (v16.02.00.11)?
We recently identified a few issues in the current market version 16.02.00.01 of LEAP Bridge Concrete. The details of the issues are as shown below. We have fixed those issues, and created a maintenance patch (v16.02.00.11). If you need this patch, please…
LEAP Bridge Concrete DW loads
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…
LEAP Bridge Concrete Reactions
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.
LEAP Superstructure - Prestressing Development Length
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…
LEAP Bridge Substructure/RC-Pier LFD Live Loads in the Negative Moment Region
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…
