Expansion Bolt vs Anchor Bolt,
(OP)

Hi, what is the difference between expansion bolts and anchor bolts? Both to be put after (drilling) because there is already existing concrete.
In the plan above. It specifies expansion bolts. I plan to get the Hilti anchor bolts because of tested specs. Are their anchor bolts also considered expansion bolts (it expands at the ends)?
Also for application like it.. do you recommend chemical bolts? In your experience, what is the best Hilti model for it?

While it is good to get advice from a forum such as this, you are asking for a selection of bolt type without letting us know the loads, the temperature conditions, the concrete strength and equally important, the experience level of the installers.

An expansion bolt is a torque-controlled fastener. It screws into an insert that expands. Hilti Kwik Bolt TZ are common.
An epoxy adhesive anchor, or chemical, is basically glued to the concrete. Hilti HIT-HY 200 is common.
As for the anchor that you select, point it out to your reviewer.

It's written anchor bolts. Designer gave and said no specific spec but just 16mm anchor bolts. So I wonder if I can use the Hilti mechanical bolts. Which model do you usually use on this central support application (that is not column)?
