  • LEAP Bridge Concrete - CONSPAN, CONBOX, RC-PIER, CONSPLICE, and GEOMATH inside OpenBridge Designer CONNECT Edition

    LEAP Bridge Concrete is a consolidated version of LEAP Bridge Enterprise , plus all LEAP standalone products including CONSPAN, CONBOX, RC-PIER , and GEOMATH. In addition, CONSPLICE is also included as an add-on tool. The following new features have also…
  • 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…
  • 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.
  • 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…
  • 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 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…
  • 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…
  • 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…
