Mechanical shock is a common problem that is present in many situations, such as ground motion, blast, explosions, crash, and impact. The development of passive, active, or adaptive control and isolation strategies for ...

Seismic isolation of high-rise buildings presents an opportunity but also a challenge to seismic isolation, a technique mostly used in the past in low and moderate-rise buildings. It turns out that under certain conditions ...

This investigation deals with the analytical formulation and experimental validation of a prestressed reinforced concrete seismic isolator with kinematic constraints at both ends. The kinematic isolator was proposed initially ...

Nonlinear isolators with high-static-low-dynamic-stiffness have received considerable attention in the recent literature due to their performance benefits compared to linear vibration isolators. A quasi-zero-stiffness (QZS) ...

In this investigation the pathogenicity and immunogenicity of seven isolates of Paracoccidioides brasiliensis were compared. The pathogenicity of each isolate was determined by 50% lethal dose estimations and histopathology ...

The aim of this paper is to show, in a explicit way, a set of isolated real points with uncontable closure. The advantage of our construction is the fact that we can get a clear idea of how is this set distributed among ...

A novel approach for two-dimensional modeling of elastomeric bearings using three springs in parallel is presented. This simplified element model considers as follows: (1) an elastoplastic spring with a smooth transition ...

Because of the booming wine industry in some seismic countries such as the US, Chile and Argentina, seismic protection of wine storage systems is of practical importance. In this study, the dynamic response of thin-walled ...

This article Summarizes the work done by the authors in seismic isolation over the past six years in Chile. First, a general evaluation of the optimal values of the yield level of the isolation system is performed, focusing ...
