Resumen
Practical engineers should gain confidence in base isolation as an alternative to stiffening, a possible design approach for new as well as for existing buildings even under rare seismic conditions (in large corner period areas and for pulse-type seismic records). This article presents the structural benefits of curved surface sliders on a specific, existing building application. Moreover, authorities should be encouraged by the information included in this article, to emphasize alternatives to the stiffening design approach even under such special seismic conditions.
