Midas Technical Live Session 4: Rail Structure Interaction (RSI) Analysis

[@nishanktyagi09]

Hello Team Midas, Thankyou for the detailed explanation for the problem. whereas there is a query, while analyzing the individual models we should see the same results as shown in the excel ( report created by wizard), but in the model "rsi 1_Add2_RotationAngle_Mov3" the rail stress just above the pier are above 90mpa whereas report generated does not captures that. Can you please explain what is the reason for not reporting this stress.

Hi Anuj, thanks for the webinar. I am modelling the bridge in your example for my learning and when I analyse the model using the report function of the Rail Structure Structure Interaction Wizard its producing an warning message early on in the analysis which says 'There is no base file!!'. Do you know what this message means and where I may be going wrong? Thanks

A very basic question, can the RSI analysis be made for curve tracks, if the basis track parameter is known to me or may be assumed suitably?

Thanks Anuj for the nice webinar. Can you please tell me how to proceed with RSI analysis for the junction area where blasted track and slab track meets? I mean near the depot the track is at grade and ramp is there... When the track is going from at grade to elevated ramp. How to perform RSI analysis? Please share is you some study material as well if you have. Thanks in advance.

Hi Arnab, the essential difference between the track on ballast and track on slab will be the stiffness of the multi-linear link between the rail and deck. This can be taken care by Midas Civil's rail track analysis model wizard. Here in the boundary tab we can define the stiffness for loaded and unloaded condition and position of ballast or slab along the bridge. The software will generate the multi-linear elastic link with appropriate stiffness, simulating ballast or slab.

How we determine the support stiffness and track stiffness?

please can you share the reference from UIC /Eurocode for compressive stress limit of 92 Mpa in case of concrete bed. As mentioned in the video at 14.44 min.
