Supports along single member

Hey, I’m having a hard time figuring out how to place supports along a single element. Use my bad drawing of a free body diagram as reference. I know I can split the element into multiple elements to place supports in between them, but then the internal forces doesn’t act right. Is my vision possible to accomplish? And if so, how?

If you split a beam into multiple parts, the beam will still behave as though it is rigidly connected unless you define joints in the elements. Can you share your definition?

Hi. My claim is based on the word of my professor (perhaps I misunderstood), but I just tried it out, and it works exactly as I wanted it to, so all good. Please forgive me for wasting your time.

no worries, it is always good to test it out to see if everything works.
