click on GameObject --> Create Other --> Ragdoll... and just Drag & Drop the Model in the same place

To ragdoll it select the object–>Add component–>Physics–>Rigidbody
If you want forsay a brick falling to explode or something use this and script what you want to do after it:)
function OnCollisionEnter(theCollision : Collision)
