Experimental and Analytical Study of a Combined Sliding Disc Bearing and Helical Steel Spring Isolation System
A sliding isolation system consisting of Teflon disc bearings and helical steel springs is described. The system has been evaluated in shake table tests of a six-story, quarter scale, 52 Kip model structure and found to ...
Experimental Study and Analytical Prediction of Earthquake Response of a Sliding Isolation System with a Spherical Surface
This report describes the results of an experimental study of the behavior of a sliding isolation system with a spherical surface installed in a flexible structure with large aspect ratio. A series of shake table tests was ...
Viscous Dampers: Testing, Modeling and Application in Vibration and Seismic Isolation
A fractional derivative Maxwell model is proposed for viscous dampers which are used for vibration isolation of piping systems, forging hammers and other industrial equipment, as well as for vibration and seismic isolation ...
Secondary Systems in Base-Isolated Structures: Experimental Investigation, Stochastic Response and Stochastic Sensitivity
This report first describes a series of experiments conducted on the shake table at the University at Buffalo, whereby the performance of secondary systems attached to a scaled, base-isolated six story frame was monitored. ...
