TESTS OF FRICTION ENERGY DISSIPATORS FOR SEISMIC PROTECTION OF BUILDINGS
This paper presents unidirectional shaking table tests of two steel frames; they are reduced scale models of two building structures with one and two floors, respectively. Such frames incorporate friction dissipators at every floor. The inputs are sine-dwells and artificial and registered earthquakes; some of the sine-dwells generate near-resonance motion and some of the earthquakes contain pulses corresponding to near-fault effects. The main objectives of these experiments are: (i) to collect a wide range of results useful to calibrate a numerical model derived by the authors, (ii) to contribute to clarify some of the most controversial issues about friction dissipators (introduction of high frequencies in the response, behavior for inputs containing pulses, capacity to cut resonance peaks, self-generated eccentricities), (iii) to understand better their dynamic behavior, (iv) to give an insight on the feasibility and reliability of using simple friction dissipators for seismic protection of building structures and (v) to characterize the hysteretic behavior of these devices.
