Article
In this paper, a novel device called the “ISO3D-2G” is proposed for a three-dimensional vertical rocking isolation (VRI) system. The VRI system works by isolating critical vibration sources, e.g., earthquake events and operational high-frequency vibrations. In this work, only its performance as a seismic isolation system is studied. The ISO3D-2G is...

Legged thin-walled liquid storage tanks have shown in many cases poor seismic performance during several strong earthquakes around the world. The damage and collapse of these containment structures lead to the loss of the liquid, such as milk, wine, and others, thus generating significant economic losses. This damage may also affect components alon...

A Mexico City building built in 1958 located on soft soil is analyzed, which has been damaged by the 1985 Mw 8.1 and 2017 Mw 7.1 earthquakes. Buildings in the same area and similar structural systems collapsed in these earthquakes (210 in 1985 and 38 in 2017). To perform the mathematical model, a structural identification was carried out using a re...

In previous research presented in the 16WCEE, the seismic response of a typical 19-story building for residential use in Mexico was analyzed. The structural system of the structure is based on reinforced concrete frames and walls with a fixed base. Design alternatives were proposed adding seismic isolation at one and two interfaces, presenting upli...

Most used seismic isolation systems provide to the structure of horizontal isolation, just like elastomeric or frictional devices does, but the vertical component of excitation is still transmitted directly into the structure and vertical isolation is needed in some cases. Vertical isolation is needed also for vibration control of industrial mechan...

This paper analyzes the polyurethane material that can be used for the construction of seismic isolation devices based on rolling of elastomeric spheres. Such isolators could be used in low-income countries. Uniaxial tensile tests were performed on dumbbell-shaped polyurethane 95 ShA specimens under two different loading protocols. Protocol 1 consi...

This paper presents the numerical and experimental evaluation of a vertical‐rocking isolation (VRI). This evaluation is done by 1‐D shaking table tests performed on a full‐scale legged storage tank of 3000‐liters capacity and its representation through a simple yet representative rigid lumped‐mass model approach. The isolation system setup consiste...
Patent
The invention relates to a device for three-dimensional vibration insulation between structures or equipment and the foundations thereof, which comprises: a hinged hexagonal metallic frame formed by an upper píate for ancho ring to the structure; a lower píate for supporting on the foundations and at least one pair of hinged arms oppositely incline...
