Preliminary Design of Frictional Impact Isolator with a Rubber Core Inside

Abstract

In the Argentine Republic, more than two-thirds of its territory is at seismic risk and with minimal seismic protection. Studies carried out on local and regional seismicity have demonstrated the high seismic danger of important provinces in western Argentina, an example is Mendoza and San Juan, where the province of Mendoza, with a little more than two million inhabitants, has an important seismic history. In the last 200 years, no less than 15 earthquakes have occurred, causing varying levels of damage to buildings and in some cases loss of human life. The best-known historical precedent is the earthquake of 1861, which caused the total destruction of the city and caused the death of 60% of the people who lived in the city. The technological advance of recent years has made it possible to have new developments and technological innovations that tend to reduce and control the effect of destructive earthquakes on buildings located in regions of high seismic risk. The work consists of the preliminary design of a frictional seismic isolation device for essential equipment and contents. The theoretical framework and the capacity to withstand seismic events are developed. The work is completed with, i) information on the response of the locally designed equipment to sensitive earthquakes that occurred in the region recorded by the Ceredetec seismic instruments, ii) general characteristics of the seismic isolation device in relation to its particular earthquake dissipation mechanism. energy.
