Hi all. How does RM Bridge consider the effect of cable sag? Best regards.

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.

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.

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…

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…

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…

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…

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…

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…

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…

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…

LEAP or RMBridge or STAAD pro.

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?

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…
