Abstract

A new viscoelastic-type connection consisting two steel plates interlocked by a single tooth and elastomeric material was developed and tested recently at the Earthquake Laboratory of the Arizona State University. Based on these experimental results, a Kelvin-Voigt type model was developed to simulate the behavior of the connection. By comparing the stress-strain curves of the model with those obtained from the tests, it was found that the durometer of the elastomeric is the predominant material parameter. A numerical method is presented to analyze the response of framed structures with these new viscoelastic-type connections and the effectiveness of the device is studied from the analytical results. Some numerical problems in the implementation of the model are also discussed.
