Isolation Technique in Bridge, Building

Abstract

Seismic Isolation is simple structural design approach to mitigate or reduce earthquake damage potential. It is easiest to see the principle at work by referring directly to the most widely used of these advanced techniques, known as ‘Base Isolation’. A base isolated structure is supported by a series of bearing pads, which are placed between the buildings and building foundation. Base isolation has now been used in numerous building in countries like Italy, Japan, New Zealand, and USA. Base isolation is also useful for retrofitting important buildings (like hospitals and historic buildings). By now, over 1000 buildings across the world have been equipped with seismic base isolation. In India, base isolation technique was first demonstrated after the 1993 Killari (Maharashtra) Earthquake. Two single story building (one school building and another shopping complex working building) in recently migrated Killari town were built with elastic base rubber isolators laying on hard ground. After the 2001 Bhuj (Gujarat) tremor, the four story's Bhuj healing facility building (hospitals) was built with the base segregation strategy called isolation technique. Seismic separation is a moderately recent and advancing innovation technique. In this paper I am going to investigate of Base confinement framework segments with contextual analyses of case studies.
