Abstract

The concept and the functionality of the Stiffness Decoupler for Base Isolation of Structures, (SDFBIS, U.S. patent No. 5,660,007, August 1997, and No. 5,386,671, February 1995), and the methodology for the numerical simulation of the dynamic responses of structures, the computer simulated accelerogram and the recorded time histories of the response accelerations of the 14' by 9' by 18' tall model steel structure under the application of an 88% of the ground motion of the Northridge 1994 Earthquake, (shaken by the KSU shaking table), will be presented for comparison. The performance of the SDFBIS system, the efficiency of the numerical algorithm and the sensitivity of accelerometer s Model 799M and 731A model of Wilcoxon Research will be presented in the concluding remarks.
