  • 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…

  • 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.

  • 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 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…

  • 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…

  • 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…

  • 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?

  • RCPier crashes on open

    I am using Leap Bridge Enterprise v14.00.00.09 in a Win7 environment. When I open the Geomath and Conspan modules, they work fine. When I open RCPier, it gets to a screen which says "Loading Project File" and then crashes, and it sometimes gives me a…

  • 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…

  • LEAP bridge problems
