  • non-linear material analysis in RM Bridge

    Hi all. How is non-linear material analysis n RM Bridge understood? Best regards.
  • the effect of cable sag

    Hi all. How does RM Bridge consider the effect of cable sag? Best regards.
  • allowable displacement of towers under live load

    Hi all. In the design of a cable-stayed bridge, what is the allowable displacement of the A and H shaped towers under live load? Best regards.
  • short-term and long-term composite cross-section

    Hi all. In composite steel girder bridges with concrete decks (continuous span bridges), does RM bridge automatically Calculator effective width of deck to calculate short-term and long-term composite cross-sections? best regards.
  • Steel composite bridge

    Hi all. I hava some question about steel composite brige as follows: 1. To calculator stress point of section, Rm Bridge automatic use short-term section for live load and load case type Non-permanent and use long-term section for load case type Permanent…
  • upward deflection of the continuous bridge structure

    Hi all. In continuous beam structures, the allowable downward deflection of the bridge under HL93 load is L/800. So may I ask what is the upward deflection of the continuous bridge structure under HL93 load? best regards.
  • Use No tens and ReloadSup functions in RM Bridge

    Hi all. in steel girder bridges combined with concrete decks (continuous span girder bridges). If the concrete deck is not in tension and the combination of internal forces according to the Service limit state is service.sup, then use the ReloadSup function…
  • allowed deflection of the bridge under the effect of live load

    Hi all. Nice to meet you. I have a model steel composite cable-stayed bridge with 6 span continuos by Rm Bridge V8, 2 side span have 150m, 4 main span is 300m. I don't known about allowed deflection of the bridge. I use AASHTO LRFD standard. If you…
  • Reinf crack for prestressed concrete

    Hi all. I have a question about Reinf crack for prestressed concrete as follows: If you calculator stress bot of section beam in MinMz_Service exceeding allowable stress tension limit is 0,5 x sqrt(f'c), you can calculator reinf area to control crack…
  • 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…
  • 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…
