We construct a class of analytic solutions with two free parameters to thefive-dimensional Einstein field equations, which represents the collision oftwo timelike 3-branes. We study the local and global properties of thespacetime, and find that spacelike singularities generically develop after thecollision, due to the mutual focus of the two branes. Non-singular spacetimecan be constructed only in the case where both of the two branes violate theenergy conditions.
