Paper Abstract
This paper will discuss analysis and design of large ground based telescopes for seismic hazard. Seismic hazard is an
important issue for both the observatory and the telescope structure. Properly defined seismic specifications are vital.
These specifications should include performance objective that matches performance levels and probabilistic based
hazard levels for operational and survival conditions. The paper will discuss specific tools that utilize results of existing
seismic hazard assessment programs and can be used for initial seismic assessment during site selection. In the final
stage of site selection, site specific probabilistic seismic-hazard studies that account for local geological settings and
active faults should be used. The results of these site specific studies usually include response spectra and time history
records in horizontal and vertical directions for operational and survival conditions. Different methods to analyze the
telescope structure for seismic loadings, such as, equivalent static analysis, response spectrum analysis, linear and
nonlinear time history analysis, are discussed. Devices that mitigate seismic forces and/or deformations are also
presented.
