capping bridge stiffness
i am analyzing a 2 buildings that will be connected by a capping bridge. are there any quick ways to calculate the  required stiffness of the bridge such that it will force the buildings to behave coupled?
thanks
i think first you need to define "capping bridge", and explain in what sense you mean the buildings will "behave coupled".  a description of the buildings is also required.  but i think the answer to you actual question is -- no, there is no quick way.
when i meant behaving coupled, i meant how stiff the linking element will need to be such that the buildings don't move out of phase, meaning buildings moving in opposite direction to each other. the buildings are 30 stories tall with a plan dimension of about 120 x 230'
