Dynamic Analysis (time history analysis)

Question:

Dear, Support Team

We are currently working at high speed Railway Bridge project. I have a questions about time history analysis. We would like to create grillage mode for our bridge for time history analysis and I don't think that point load will be appropriate to this type of model. I would like to know if it is possible to applied other typ of load for time history analysis. I would like to make transverse distributions and applied load as line load (in transverse direction). I found out that at midas it is option as 'Time Varying Static Loads' and I would like to know if it is going to work the same way as 'Dynamic Nodal loads'

Regards

Answer:

Hello ,

Yes, you can use the Time Varying Static Loads to apply a UDL in the Time History Analysis. However, unlike the Dynamic Nodal Loads which are applied to a node directly into the Time History Load Case, here you will need to define a static load case for each independent UDL which you want to apply in the TH Analysis with a different time or magnitude.

Kind regards,
