I'm the final student and stuck in my project. I want to put the rotational spring under the wall, but I don't know how to model it with SAP2000 as I'm new to the application and what kind of data I need to model it?
Thank you so much.
As someone already mentioned about this, you need the spring constant, which depending on your units might be kip*in/rad or an SI equivalent. Better consult the available manual in the application.
