22-20 ANALIZA FEM A SISTEMELOR DE IZOLARE SEISMICĂ CU SUPRAFAŢA DE ALUNECARE GENERATĂ DE FUNCŢII POLINOMIALE
Earthquake isolation systems are devices located at the base of
overhead structures (civil works), which have the goal to take off the oscillating
period of this compared with ground, during an earthquake and decrease the
transmitted energy using frictional dissipation. The results of the study
presented of this paper relieve the possibility of using sliding surfaces
generated by polynomial functions by using an intermediate neoprene element
between the sliding surface and the slider.
