  • STAAD.Pro Running Live Load on a Plate error

    Slab Design 2 Deck Analysis 2.std Good Morning, I am designing grade beams (in the transverse direction) with a plate on top (acting as the deck). I have generated moving loads to go across the beams. When I look at the output files, the bending moments…

  • STAAD.Pro V8i Concrete Slab & Grade Beam Design

    I am currently designing a deck slab, supported on grade beams (pile caps), on piles. I have created my beams, set the properties, and put a plate on top to act as the deck. My supports are the locations of the piles. I am having trouble obtaining the…

  • 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…

    The side-by-side option in CONBOX allows you to apply the provisions of LRFD Art. 4.6.2.2.5 Special Loads with Other Traffic. SBS: Side-by-Side live load responses use the following equations: · LLRsp = LLRsp(PermitLL) * DF1/Z + LLRsp(DesignLL…

  • 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…

  • 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…

  • Re: Beava

    Eduardo, Based on the brief information provided, you seem to have selected the correct load cases with the corresponding steel design codes. But jsut to clarify, the "AASHTO Standard Specification for Highway Bridges" contains both ASD (allowable…
