SDOF subjected to a seismic input

This is the study of a SDOF subjected to a seismic input

The equation of motion is solved with the hypothesis that the acceleration varies linearly in the step.

At the end of the calculation a very nice animation is performed.

You can choose 3 different constitutive models:

- linear elastic

- elastic - perfectly plastic

- Armstrong - Frederick cyclic hardening plasticity

You can choose among 20 Italian earthquakes.

I suggest this choice: Armstrong - Frederick with earthquake 16
