  • 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…

  • How do I install LEAP RC Pier v14.0019 with our selectserver?

    How do I install LEAP RC Pier v14.0019 with our selectserver? It used to install fine. Now when we try to install on a PC,it asks for the correct activation and selectserver info which we enter then it says its activated, When we click on the executable…

  • Shrinkage Strain Load & Moment capacity error - LBC Substructure

    I have bent that is being constructed in two phases so some shrinkage will happen on the first phase before the next phase is constructed. In the final condition, I could assume the entire shrinkage strain is applied to both sections but that will be…

  • Does RC Pier check shear friction in the pier cap (AASHTO 5.7.4)?

    Does RC Pier check shear friction in the pier cap (AASHTO 5.7.4)? I've looked in the output reports and didn't see reference to this spec section. I've also looked in the application help interface and couldn't find it. Note: my application version…

  • RC-Pier LEAP Bridge Concrete SDCL

    Hello, Is LEAP Bridge concrete / RC-Pier capable of having a structure simple span for dead load and continuous for live load (SDCL)? Thanks.

  • How to access RCPIER in LEAP

    To access RC-PIER in LEAP users just need to select the Substructure Tab in the Project and hit the Substructure button, as indicated by the red arrows in the screenshot below.

  • Pier View Direction

    Substructure allows users to define a pier looking at it in an upstation view or in a downstation view. This affects the way cap/column/footing geometry and loads are defined. When pier is defined in upstation view, it is defined looking at the…

  • Column Spring Supports

    By default columns are fixed at bottom. However, program allows users to specify a spring matrix at the bottom of every column if partial fixity is desired. Program provides two options for this. First option allows to define diagonal entries in the spring…

  • 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…

  • RC-PIER loads are erased if the geometry of the pier is changed

    In RC-PIER loads are generated based on dimensions of structural elements of the pier. Making changes to geometry invalidates generated loads. In this case the program will automatically delete existing loads. In this case the designer should re-generate…

  • How can I output the RC-Pier STM analysis for all Load Combinations to Excel?

    How can I output the RC-Pier STM analysis for all Load Combinations to Excel? In the analysis tab, i tried using the "Print..." button and choosing "All combinations to Excel File". This appears to only output analysis related to the entire hammerhead…

  • LEAP Bridge Pier Load Generation

    I have several questions and need clarification on several aspects of the load generation in LEAP Bridge for substructure design. 1. For WS, is the "barrier height" in the Geometry tab used for any other purpose besides determining WS? I want to use…

  • RC PIER END BENT DESIGN LOADING

    Good morning, Right now I'm developing an analysis for an end bent and I was concerned about if just with the inputs of the geometry for the back wall would automatically be considered as a self-weight loading or do I need to include it's reaction…

  • Shear and Torsion Design for RC Pier

    Hello, I have a question regarding shear and torsion design in RC Pier. In RC Pier, under Analysis --- AD Parameters---Shear and Torsion Calculation , there is option which says " Shear force is equally distributed among stirrups ". I read the Help…

  • Leap Bridge Concrete Version 20.00.00.46

    Hello, I have been experiencing a substantial amount of instability/crashing in LBC 20.00.00.46. The program will randomly freeze and become unresponsive. This happens when I run an analysis, look things up in the help manual, attempt to save, and many…

  • 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…

  • LRFD 8 - Wind Load Auto Generation

    When using the "Generate Default Load Combination" feature, the load combinations generated are using different factors, like : - 1.4 for WS for STR GP 3, - 0.4 for STR GP 5, - and 0.3 for SER GP 1. LRFD 8 specifies 1.0 factor for all WS regardless…

  • Back to the "Cap as continuous beam" after save "Piles integral with cap"

    I am looking for pile reaction as piles integral with cap then save the file. next time open the file, it is back to "Cap as continuous beam" How can i fix this situation?

  • Leap Bridge Concrete - Wind Load on Live

    Hello, When attempting to create the load combinations I receive the following message - "Dependent loads of type WL and master loads of type WS are not equal in number. Please specify same number of two loads when cross combinations option is turned…

  • Unable to Auto Generate Live Loads in Substructure Design

    Hello, I am designing a multi-column pier substructure for a bridge. The substructure model is connected to the superstructure so I am able to auto-generate the superstructure dead load, Braking load, and Permit Live Loads. However, the button to generate…

  • Auto Generated Live Load Cases in LEAP Bridge Concrete - Substructure

    I am designing a hammerhead pier using the substructure module in LEAP Bridge Concrete. The geometry is a little odd...it's a hammerhead cap on a circular column. To compare the results for the cap design from the conventional sectional design & strut…

  • RC-PIER Material Properties tab

    I'm designing a pile cap abutment in RC-PIER, but I'm unsure how to input the material properties. In the material properties tab, there are inputs for concrete cap, concrete footing, and concrete pile. I have a concrete cap on steel H-piles. RC-PIER…

  • Upgrade to LEAP Bridge Concrete!

    LEAP Bridge Concrete now includes all of the individual LEAP modules that were previously sold separately (CONSPAN, CONBOX, CONSPLICE, RC-PIER, and GEOMATH.) With LEAP Bridge Concrete you can create 3D bridge models, perform analysis, design, and load…

  • RC-PIER Live Load Auto-generation verification

    Does anyone have calculation verification for the live load auto-generation function in RC-PIER? Or has anyone else had problems verifying the LL output from RC-PIER?
