Shock Response Spectrum, Q=10

1940 El Centro Earthquake North-South Component

* * *

The Matlab scripts srs_tripartite.zip calculate the shock response spectrum of a base input acceleration time history.

The results are plotted in tripartite format. Acceleration, velocity, and relative displacement are each represented as a function of natural frequency on the same plot.

srs_tripartite.m is the main script.

The remaining scripts are supporting functions.

The resulting velocity is actually the acceleration pseudo velocity shock spectrum (APVSS) which is obtained by dividing each acceleration SRS value by omega, where omega is the natural frequency in (rad/sec).
