• Question Regarding CONSPAN Shear Design

    Hi, dear friends, please help me with this following question. I read the tutorial of CONSPAN and it tells that CONSPAN does the longitudinal reinforcement code check (according to AASHTO LRFD 5.8.3.5). Where could I check this code check result in…
  • CONSPAN Tension Stress Limit Code Check

    Hi, Dear Friends, I was checking a CONSPAN model and I found one of the stress limits was not checked by CONSPAN. Is this a bug or actually I understood the code wrongly? See the attached pic, the "-0.501" is over the limit "-0.276" but it is not red…
  • Detensioning Failure

    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…
  • Positive Envelope Stresses Calc

  • CONSPAN Flared Girder Alignment Dialog

    Hi, guys, I have a question regarding "Bridge Alignment" for "Flared Girder" in CONSPAN. The help file tells "CONSPAN assists the design by computing the distance between supports along the centerlines of the bridge and, if desired, along the centerline…
  • QUESTION ON CONSPAN FLARED GIRDER GEOMETRY TAB

    Hi, guys, I have three questions regarding CONSPAN flared girder modeling. 1. In "Bridge Component Layout" dialogue, does the "Bearing" mean the center line of the bearings? 2. As you can see in the picture above, it is a curved bridge. How do I…
  • CONSPAN: how to model staggered diaphragms in skewed bridge?

    The diaphragms are staggered between girder bays and perpendicular to the girders. The program only allows me to create a diaphragm line cross all the girder bays, either skewed or non-skewed. How can I stagger them between the girders? Thanks.
  • Conspan Lateral Beam Stability During Lifting and Transportation

    I am investigating lateral beam stability during lifting and transportation for a beam designed in Conspan. I am concerned about how the program is calculating the lateral deflection caused by wind in both cases of lifting and transportation. I am able…
  • Customized output reports

    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?
  • Customizing the section at End girder

    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…
  • Time-Dependent Loss model used by Conspan

    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…
  • Importing Permit Loads from Conspan to RC-Pier

    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…
  • Dimensions in Conspan

    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.
  • Double Truck in Conspan

    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…
