  • 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.

  • allowable deflection of a suspension bridge

    Hi all. Can you tell me what the allowable deflection of a suspension bridge is? And what standard is this deflection limit based on? 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…

  • 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…

  • LEAP Bridge Steel crashes when I "Run Design Check"

    I am designing a pedestrian bridge, so I deleted the Live Loads and added a pedestrian load that is applied to a sidewalk that covers the deck. The analysis runs for both line girder and grillage, but when I try to run the design check everything goes…

  • 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…

  • Design of Hanger Reinforcement of Muli-Column Inverted Tee bent

    Recently, I have started working on Leap Bridge Concrete V 17.01.01.11 , and we start questioning whether the hanger reinforcement check has been considered or not on this version, AASHTO 5.13.2.5.5. I couldn't see anywhere checking the combination of…

  • RM Bridge - Stress calculation for asymmetric sections

    Our firm noticed, during the design of a hollow box bridge with inclined top slab (curved bridge with 7% transversal slope), that elastic stress calculation performed by RM bridge is not correct. In fact, even if it's possible to model generic cross sections…

  • RE: Sample Tutorial for RM Bridge Concrete Design Code Check?

    Hi, Usually you can find RM Bridge Concrete Design Code Check only at the Part2 documents. Check the image below for your reference. Sample tutorials are at File\Examples\TrainingExamples. If you select Training Example 02b. Prestressing AASHTO and…

  • Which software platform is comparable to CSIBridge if not better?

    LEAP or RMBridge or STAAD pro.

  • 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?

  • CONSPAN Tension Stress Limit Code Check

    Hi, Dear Friends, I was checking a CONSPAN model and I found one of the stress limits was not checked by CONSPAN. Is this a bug or actually I understood the code wrongly? See the attached pic, the "-0.501" is over the limit "-0.276" but it is not red…
