摘要

pThe device for protecting a structure against the effects of dynamic stresses and especially stresses produced by earthquakes comprises a system of friction supports constituted by seating blocks associated respectively with the structure and with the foundation floor. The blocks are applied against each other and capable of relative displacement in frictional contact. The coefficients of static and dynamic friction of the contact surfaces range from a minimum value of approximately 0.08 to a maximum value of approximately 0.5./p[US4121393A]
