Non-invasive passive control of steel MRFs with rotational friction devices

Research output: Contribution to conferenceOtherResearchpeer-review

Abstract

The efficiency of a passive control technique is analyzed in the case of the seismic retrofitting of a steel moment-resisting frame (MRF). A significant part of the energy input by the earth¬quake is dissipated through rotational friction devices, located around beam-column joint zones where inelastic behavior is expected. An experimental cyclic test has validated the hysteretic restoring force model of the device, which has been adopted to numerically model the device in a computer code for the nonlinear analysis of steel MRFs. As an example of application, a frame designed by Tsai and Popov in 1988 is analyzed; the po¬sitive effect of retrofitting, for both the serviceability and the ultimate limit state (SLS and ULS), is measured by the reduction in local and global ductility requirements.
