- The Structural Engineers Association of California (SEAOC) developed in 1990 the document 'Tentative General Requirements for the Design and Construction of Seismic Isolated Structures'. The SEAOC document specifies analysis procedures for seismically isolated structures, including a static and dynamic analysis procedure. Described in the report is a study that concentrated on verifying these procedures for sliding seismically isolated structures. The study involved the following: (1) evaluation of the response of sliding seismically isolated structures with stiff and flexible superstructure; (2) comparison of dynamic analysis results with the results of the static analysis procedure of SEAOC. The main conclusion reached is that a degree of conservatism exists in the SEAOC static analysis procedures. Specific cases are studied and the differences quantified.
