Lateral Stiffness - Building frequency
Lateral Stiffness - Building frequency
(OP)
Hi,
I'm trying to get an idea of a buildings frequency, i've got a 70m high tower with a concentrated mass at the top.
Is there a rule of thumb when first considering its sway sensitivity?
Can i use f=1/2pi * sqrt k/M ? How do i go about determining it's lateral stiffness?

It's an airport control tower, so its basically a 70m stairwell and then 3 cabs at the top.
