Dynamic analysis function selection

Question:

Hello,

I am having trouble using the dynamic analysis functions within Midas. I have used these previously, however, the ability to load time history functions for dynamic nodal loads seems to be blocked.

Is there a reason for this? I have attached the file also.

Can you please help?

Answer:

Hi,

You have selected Acceleration as Time Function Data Type. Acceleration and Normalized Accel. can be applied using the 'Ground Acceleration' function. Force and Moment can be applied using the 'Dynamic Nodal Load' function. Normal using the 'Time Varying Static Load' function. In your case, Force would be appropriate to apply using the Dynamic Nodal Load function.

Regards,

DK Lee
