Hi All,
I want to investigate the settlement behavior on a segment of a railway track under repeated train loading. Do you have any idea how to apply a certain moving axle load repeatedly? Thanks in advance.
Hello, Mahammad
I think the computer program will be able to do it.
Muhammad Abdur Rahman Using the "Dynamic load" option in the Loads menu, you may replicate recurrent train loading in Plaxis. This allows you to define the load as a function of time, allowing you to specify that the load be applied numerous times with a time gap between each application.
Follow these steps to configure a repeated train loading in Plaxis:
Create a new project and specify your soil's shape and material attributes.
Select "Dynamic load" from the Loads menu.
In the Dynamic load input dialog, indicate the load type (e.g., point load, line load, surface load) and the load location.
Enter the magnitude and direction of the load as a function of time in the Load input section. You can, for example, request that the load be applied for a particular amount of time (e.g., 10 seconds) and then withdrawn for a specific amount of time (e.g., 5 seconds) before being applied again.
Enter the time step for the analysis in the Time step input area. This should be small enough to capture the dynamic reaction of the soil or structure, but not so small that the analysis becomes too lengthy.
To begin the analysis, click the "Calculate" button. Plaxis will apply the required load at the defined time intervals and compute the soil or structure's reaction.
I hope this was helpful! Please let me know if you have any queries or require any other support.
