Response of a Single-degree-of-freedom System to Base Excitation

sdof_base_image

These Matlab scripts calculate the response of a single-degree-of-freedom system to base excitation:  sdof_base.zip

sdof_base.m is the main script.

The remaining scripts are supporting functions.

The base excitation may be a half-sine pulse, terminal sawtooth pulse, arbitrary pulse, or a PSD.
