Abstract: Rolling isolation systems (RISs) have been used extensively to protect bridges, buildings, and equipment from earthquake-induced ground and floor motions. RISs are attractive in a performance-based design context because ...

Abstract: The motion of a slender rigid block resting on an isolated base supported by rolling bearings is analyzed. This paper investigates what happens when the ground upon which the isolation system rests is subjected to a ...

Abstract: Apparent weakening is the softening of a structure’s apparent stiffness by adding negative stiffness to the overall system, which has the benefit of reducing the peak accelerations and base shears induced in the structure ...

Abstract: Since 2006, the number of M3.0 and larger earthquakes occurring in Oklahoma has increased dramatically. Four M5.0 and larger events have caused damage to residential structures, which raises a concern about the potential ...
