Abstract
In order to counteract the soil sudden movements as a result of seismic
actions, a disconnection between the primary components of a specific
structure was needed, so that the efforts can not be transmitted on vertical
direction. Thus occurred the need for isolation systems that can be
attached to the base of structure, between foundation and superstructure.
The isolation systems based on dry friction have been successfully used
worldwide. At the beginning, simple isolation systems with sliding on a
single spherical surface were used and later double systems have been
designed which have two main sliding surfaces. In this paper it is shown
the working principle of double isolation systems based on dry friction
depending on the main variables involved and the linear forcedisplacement
diagrams obtained from the case studies using different
values.
