Las pruebas demuestran que los coeficientes de fricción son independientes de las frecuencias, solo de las cargas.

El trazo rojo corresponde a las aceleraciones del terreno, el verde a las transmitidas por el Filtro Sismico

El trazo verde en la grafica superior es difícil de apreciar, por lo que fué necesario magnificarlo

DYNAMIC CHARACTERIZATION OF A SEISMIC FILTER

Test Report submitted to Mr. Hector Valencia, 482 W. San Ysidro Blvd. PMB 545, San Ysidro, CA 92173.

After 45 frequency tests plus 27 accumulated

minutes during 18 earthquake simulations

Dr. André Filiatrault concluded: “For the three confining pressures considered in the test, the behavior of the seismic filter is repeatable, stable and nearly identical in tension-compression. The hysteresis loops are nearly rectangular indicating a coulomb-type frictional response. The static coefficient of friction varied from 0.08 to 0.025. The kinematic coefficient friction varied from 0.003 to 0.013.”
