Hi all. How is non-linear material analysis n RM Bridge understood? Best regards.

hi all, I have a few questions as follows: 1. During the construction of cable-stayed bridges, does the Traveler of Main Girder stiffness model always have to be considered for cable-stayed bridges to increase the stiffness of Kn girders? 2. If…

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. 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.

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 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.

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…

Hi, I'm trying to model a bridge which is very usual in Spain, prestressed concrete slab with variable edge and circular holes to make it lighter (see pictures below) Section with minimun edge, situated on center of span and with circular holes. …

Hello again, I have other question, I tried to conect OP model with RM Bridge but the program send me an error, I don't know how can I fix it Do you know how to fix the error E0053? or give an idea of what this Error E0053 wants to tell me

I am modeling a conceptual design for a cable stayed bridge. I have modeled other bridges in Open Bridge Modeler however I dont think it allows for cable stayed bridges. I know RM Bridge does. Should i Just try and do everything in RM? the main goal of…

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…

Can anybody please tell me how to investigate Whether the External tendon Profile is interrupted by each other? - in the picture above I try to set tendon profile across each other, But no any "Warning" or "Error" showing after I run my model Tha…

Hi everybody. I am currently modeling a suspension bridge with a span diagram of 125m-400m-125m. And, I have referenced how to calculate tension of main cable and hanger cable as instructed in Demo of RM Bridge V8, and I obtained a deflection of 2…

Hi everyone, I finished model and analyzer in extradosed bridge ( pictures below are my cross section and internal force ) I want to see the reults of deck (I nternal force of deck , Influence lines of deck , Ultimate load check of deck,...), Can…

Hello everyone, I needs help about create PLSYS for ultimate check and fibre stress check in stages. Like the picture below, Thanks.

Hi everyone, I am looking for the value of stresses loss in tendon (lost due to relaxation of prestressing steel, lost due to relaxation of prestressing steel,.....), Can someone tell me where is it? I'm using rm bridge v11, Pictures below are the…
