Behavior of Concentrically Braced Frames with Friction Dampers

Abstract eng:
The papers investigates the behavior of steel frames with friction dampers connected to steel braces Both numerical and experimental analyses have been conducted in order to characterize in terms of energy dissipation capacity such a type of systems and obtain an equivalent hysteric model to be used in numerical simulations. Tests have been realized for two series of brace members equipped with strain hardening friction dampers: 1st series with the brace designed to avoid buckling; 2nd series with the brace working and prone to post-elastic buckling after the damper consumed its stroke. The equivalent bracedamper model experimentally calibrated has been applied in numerical simulation of multistorey frames in order to observe their performance in comparison with conventional centric braced systems. In the paper the test results and numerical simulations are summarized as well as the resulted conclusions.
