In recent years the state of the art of seismic analysis has increased along with the delopment of technology. The developments in computer hardware and software have made analysis techniques which were formerly too expensive within the reach of most project budgets. Foremost among these has been the response spectrum analysis method for seismic analysis.

In this paper we will review the basics of equivalent static and response spectrum analyses, and their specific use in the analysis and design of an optical telescope. We will compare and contrast response spectrum analysis with the more typical equivalent static analysis, and point out conditions in which one would be preferred over the other. In addition, correct interpretation and use of analysis results will be discussed. These issues will be investigated and discussed using the ongoing VISTA optical telescope structure as an example.
