Abstract Using numerical calculation method, and compares the static load compressive capacity and impact of the
transient response for the three different materials, cast iron and steel concrete columns. Analysis data shows that the steel
column has the best bearing capacity and minimum deformation under the same static pressure. Because of damping, the
amplitude of concrete column is clearly limited, under the action of impact vibration attenuation faster, more attention in
the vibration isolation performance of high-speed high-performance processing field, using the concrete column is a better
choice.
