Twitter users suspended from the social networking site will be blocked from creating new accounts on the platform, the firm said.
The social media giant said it was taking steps to identify those previously removed from Twitter so they can be stopped from setting up new profiles.
A new safe search feature that filters out potentially explicit or sensitive content is also being introduced as part of a clampdown on abuse.
And tweets posted from blocked or muted accounts will be removed from search results.
Twitter’s lead engineer Ed Ho said the update was designed to make the platform safer for users.
He said: “Making Twitter a safer place is our primary focus.
“We stand for freedom of expression and people being able to see all sides of any topic.
"That's put in jeopardy when abuse and harassment stifle and silence those voices.
"We won't tolerate it and we're launching new efforts to stop it."
Twitter has previously faced criticism for not doing enough to combat abusive behaviour by users.
Last year it updated its reporting tools so users could be more specific when reporting content they felt was inappropriate.
This new update will also include a feature that "collapses" less relevant replies to tweets.
Twitter will now identify replies to tweets it believes are potentially abusive or low-quality and will hide these from view as a user scrolls down the screen.
Only by tapping the new "show less relevant replies" will users be able to see that content.
"In the days and weeks ahead, we will continue to roll out product changes - some changes will be visible and some less so - and will update you on progress every step of the way," Mr Ho said.
"With every change, we'll learn, iterate, and continue to move at this speed until we've made a significant impact that people can feel."
