How to change the stress limits for the intermediate bent cap from normal exposure (=0.19 sqrt(fc) <0.6ksi ) to severe exposure (=0.0948 sqrt (fc)<0.3ksi) in leap bridge concrete
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)
RCPier P-Delta Analysis increases axial forces in the column.
When running analysis with and without P-delta I noticed there is a substantial increase in the axial column force when P-delta is applied. At the node 1 the difference is about 300 kips. What could be a reason for such an increase? Any insight is appreciated…
Has Leap Bridge Concrete been updated to expand the use of Strut and Tie Modeling (STM)?
My version of Leap Bridge Concrete currently allows for the use of STM in hammerhead pier caps, but we also need that option for all cap types in multi-column bents. We also need an STM option for prestressed and CIP concrete girders in Leap Bridge Concrete…
Leap Bridge Concrete text too small
Hi, guys
I recently ran into the issues as the text is too small in Leap Bridge Concrete Bridge as shown below. Does anyone have an idea to solve this problem?
Thank,s
LEAP Bridge - RCPier Centrifugal Forces Considerations
Hi,
There are cases where centrifugal forces produce a moment that actually counteracts the critical moment in the column, does RCPier consider effects due to vehicle cases without centrifugal forces as provisioned in AASHTO Spec (See below excerpt…
LEAP RC-PIER P-delta effect in load combinations
When checking Show P-delta Effects in the Analysis tab, are the values shown represent values with p-delta effect? For example, are the column/shaft moments magnified with p-delta factor in these load combinations (with a "C" on the end of the LC#)? If…
LEAP Bridge Concrete CIP Post Tensioning Box Girder
I am working on design of a CIP Post Tensioning Box Girder. Is there any example by Bently showing design/analysis of Post Tensioning CIP girder ?
LEAP Bridge Concrete v19 crashing and wiping model
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…
Leap Bridge Concrete Video Problem?
Has anyone seen this issue in lasted version of LEAP
End user has new Lenovo P52 laptop and all drivers up to date. When rotating object you get a fan image around object as shown in screenshot.
We have another user with same P52 laptop and drivers…
Leap Bridge Concrete Wall Pier - Moments at bottom of wall
I am using Leap Bridge Concrete to design a skewed wall pier. After analyzing the pier, I noticed that for the braking force, that the sum of the forces in the z-direction at the top of the wall did not equal the sum of the forces in the z-direction at…
Self Weight Reaction
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?
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.
