Hello, I want to fill the gap between the beams and the deck by adding haunch,but I don't know what to do. If there are any related tutorials, please share with me. Thanks.

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…

I tried to check "DO Not Rotate" at the bottom of the Beam template, the slope of the beam template changed to 0, and True "Use Beam Rotation". But after doing this, the upper part of the beam formwork does tilt along with the bridge deck, but the…

Almost every span is more or less gap

I am used to the sign convention of SAP2000 but RM Bridge uses a different coordinate system (Axis 3 pointing into 1-2 plane as opposed to out of 1-2 plane in SAP2000). I would like to know the sign convention of start/end force/moment, so that I can…

Hello, I have a problem in the beam section analysis. I assigned rebars to the beam but the program says I have "0 Ast_prvd" at the transfer location and I want to know if there is any way to fix this or if there is a special setting I should look for…

Hi All, Is it possible for this template to have the follow deck edge option? And if yes what are the constraints i need to add on my template? The part which is circled in red is what i need to follow the edge of the deck. Cross section of deck…

I need to vary the width of the top flange of a Super-T girder (Australian) to follow the curved edge of a bridge deck. I can add variables to the points on the beam template but can't see how to access them/set them when the beam is used in a beam group…

Hi, I am trying to Model a Steel bridge in OBM (Not too worried about analysis, just need a 3D model). Need to find out the best workflow. There are mainly 3 Questions . (Refer to the images below) 1. What type of Bridge I should pick at the…

I have looked everywhere and can't find a clear explanation of the mechanics behind when it will and won't apply the beam definitions. Apparently the pattern is acceptable, there were no errors when creating that, but the first 3 or 4 spans, the left…

hello Everybody! At this time! Can you help me? How to draw " this member " of Arch Bridge in Rm-Bridge? Note: only is red lines in the picture.

We use LEAP Bridge Concrete for prestressed concrete beam design and load rating. We'd like to know if the program takes considerations as described in Section 6A.5.8 of the Florida DOT Load Rating Manual: 6A.5.8—Evaluation for Shear Replace subsection…

Hi Experts, I am new to OBM, I have done a few tutorials from online learning material. I wanted to know if OBM is the solution to Bridge modeling? Could you do the full detailed design of the bridge including all the components? (eg. On-Structure…

Hello, Camber and deflections are reported at 10th points along the beam. I am modelling a longer span which will require more than 10 screed points. Is there a way to toggle the number of points? Or do I have to interpolate? Thanks,

Hi everyone, I need to model a six span bridge in a curved alignment. Normally, program gives me different beam lengths in a span. I am trying to make same lengths for all beams in my target span to make easy fabrication etc. what is the way for this…

I have beams with varying spacing. When I try to make multiple beam groups within the same span, an error message says that beam groups are overlapping. Ok, so it obvious you cannot have more than one "beam group" within the same span. If I have 10 beams…

How do I modify the beam template to have skewed ends as detailed by TxDOT for skewed bridges? Currently, the beam ends interfere with the abutment backwalls. ftp.dot.state.tx.us/.../igebsts1.pdf We do not want to put the beams on a skew but rathre…

I'm doing a rating of a Girder-Floorbeam-Stringer bridge in LARS (LFR). I hardcoded the input files to automatically create check points at section changes '[SectionChangeGenerateCheckPoints] 1', and that appears to work fine except for with the floor…

June 24, 2017 Dear Engineers, Greetings for all structural engineers in the world. I'm a bridge engineer from the Philippines and currently connected in a consulting firm. I'm using Leap Bridge Concrete for less than a month and find out that it…
