I guess your
assumption is wrong. I’m not sure
what I am looking for. Is this
the equation for a pendulum since it is a concrete pier? Would this be some kind of equation
that takes into account the length and stiffness of the pier? Does someone have this equation they

FREQ OF CANTILEVER PIER
I assume you will
have no difficulty finding
the formula for a NF
of a cantilever. The problem may be
its base, which by
nature is deformable.
You will have to
increase the basic flexibility by adding
and rotation of the

have a requirement to have a cantilever pier supporting a machine to
natural frequency greater than 50 Hz. How do you calculate
natural frequency of a cantilever pier?
