Strut bars mount on top of the shocks and act as a chassis brace between both shock towers. The purpose is to reduce flex in the chassis when cornering.

Here's a good explanation on how sway bars work:

Adding to that sway bar in a way, makes your suspension stiffer, in that it tries to limit difference in height/compression between your shocks. Thus reducing body roll ..... I'm trying to keep it simple for you

yes that was more clear..now i understand what a sway bar is for pretty well..but still confused about how a strut bar differs from that..any body care to share actual facts about this not just uneducated guesses? i'd really like to learn from people who know best thanks

When a car corners, the chassis deforms (twists). Ideally, you'd want to put something like a roll cage inside the cabin to keep it as stiff as possible. But on a street car, we need that cabin space to seat passengers, so chassis rigidity is compromised.

The reason why you want to keep the chassis as stiff as possible is to ensure the suspension is working optimally. When the chassis deforms, the tires will lose some contact patch. This translates to less than optimal handling. Strut bars help add some rigidity to the chassis, give your tires more contact patch under cornering, and thus give you better handling.
