Abstract
The Structural Engineers Association of California (SEAOC) and the International Conference of Building Officials have adopted guidelines and regulations for the design of seismic-isolated structures. These guidelines and regulations specify procedures for the analysis and design of isolated structures. These procedures include a static analysis method for establishing minimum limits of design, and a dynamic analysis method which includes response spectrum and time history analysis methods. The report presents a comparison of results of the static and response spectrum analysis methods to results of nonlinear dynamic analysis for a class of seismic-isolated structures. The structures include 1-story (stiff) and 8-story (flexible) superstructures on stiff and medium soil sites and isolation systems described by twenty-two different generic nonlinear hysteretic models, which are representative of a wide range of elastomeric isolation systems.
