  • Spread footing design according to AASHTO 10.6.1.3 with multi column pier

    Hi, I am designing a multi column pier on spread footing in LEAP 20.00.00.58. I noticed that the option in A/D parameters of designing footing per AASHTO 10.6.1.3 disappears once multiple columns are specified in the model. Is this a bug, since 10…

  • LEAP Bridge Substructure/RC-Pier LFD Live Loads in the Negative Moment Region

    I am using the LEAP Bridge Substructure module to design a pier for a continuous 4 span structure using HS20 LFD loads. In the AASHTO Standard Specifications, it gives you a few options for the loading. One is that you can use a lane load with one concentrated…

  • Out-of-plane reactions distributed to pier columns for AASHTO LRFD with California option in Substructure

    A feature has been added in RC-PIER per the request from Caltrans. This feature is about how the out-of-plane reactions to external loads from superstructure are distributed to pier columns in an integral pier. For those loads which have both vertical…

  • Wind Load Auto Generation

    I have created a Leap Bridge Enterprise file consisting of a 3 span precast girder Conspan Model, and single column bents with bent caps created in RC-Pier. I'm trying to generate WS loads from the Auto Generate feature. I assume the Wind Pressure for…

  • RE: Solid Wall Pier

    Hi, I'm also trying to model a solid wall pier using LEAP RC-Pier V12.01.00.57. This version has the 'Wall Pier' option, however the generated wall design is coming up with rather impractical reinforcement layouts (#18 @ 12") oriented parallel to the…

  • Auto-generation of wind load on structure (WS) per FDOT Structures Design Guidelines (SDG) 2013

    One of the new features added to the latest RC-PIER is the comprehensive auto-generation of WS loads and load combinations per the FDOT SDG 2013: An option for WS load auto-generation is now offered under the “Loads” tab. FDOT strength and service…

  • Cannot specify Lane Loads in RC-Pier

    When manually inputting live loads into RC-Pier, how do you specify a lane load. According to the help.... "For manually input live loads in AASHTO LRFD, this screen behaves slightly different. When a live load case is added in LRFD mode and edited, the…

  • Walls in RC Pier

    I am designing a two stage pier wall. There is no option for just a wall in RC pier. Is there a way to trick the program, I have tried a couple of different options but none have worked. The top wall is tapered in both directions and the bottom wall does…
