DYNAMIC BEHAVIOR OF TWO TYPES OF ENERGY DISSIPATION DEVICES" SHEAR-PANEL" AND" OVAL-SHAPED STEEL STRIPS

Abstract:

The main objective of this study is to examine the behavior of two types of energy dissipation devices, which were installed in one story, one-bay steel frames with inverted Y-shaped braces. The specimens were subjected to slowly reversed cyclic (" quasistatic") loading, to understand their behavior when subjected to a severe earthquake, analyzing their performance under inelastic response. Experiments were performed using the on-line computer test control equipment available at CENAPRED. Emphasis is placed on the capacity of the structure to sustain large deflections and to dissipate substantial energy in its inelastic range. The advantages found when using both kinds of devices in the steel frame, comparing with the conventional braced frame are as follows:(1) High strength and high ductility can be obtained,(2) As the damage is concentrated mainly on the energy dissipation device, it could be replaced …
