Seismic Design of Structures Using Base Isolation: Qualitative Guidelines

摘要

The purpose of the report is to review the overall concept of base isolation and to develop conceptual criteria for determining the applicability of base-isolated systems. The report develops qualitative guidelines for selecting base isolation as a design strategy. Based on the base isolation design philosophy and case histories, a qualitative criteria for selecting base isolation is proposed, and the important issues which must be considered in the selection process are discussed. Various base isolation schemes are briefly summarized and their anticipated performance described. The purpose here is to characterize the various base isolation concepts, identify their relevant parameters, and discuss briefly their anticipated performance in reducing the effects of earthquakes.
