Study on the effect of the friction coefficient on the response of structures isolated with friction pendulums

Abstract

The paper presents a study regarding the effect of the friction coefficient on the behavior of structures isolated by friction pendulums. A laboratory-scale structure and its model created in SolidWorks are employed in the research. The excitation, ensured by a shaking table, follows a displacement after sinusoidal and complex rules. The study revealed the frequency at which the chosen friction pendulum assures efficient isolation is higher then 3 Hz irrespective to the friction coefficient. Experimental results coincide with those obtained from simulations.
