At my work place i am provided with a static IP. WHere in many of the important sites are blocked for various reasons. Will accessing those sites using Tor browser get detected on the main server....?
The destination will see traffic coming from a Tor exit node and not your static IP.
A list of Tor exit nodes is publicly available and therefore server operators can choose to block it, but it's fruitless to try to trace it back to origin.
If you meant if someone from your network or workplace could detect what sites you are visiting, if you are not also causing your DNS lookups to go through Tor, then your network's DNS server or any intermediate device could be logging those requests and know what sites you were trying to visit.
