And I do extend my thanks to the lecturers and professors of University of East London, who supported me with their revered wisdom and guidance throughout so as to enable me to fulfil my assignment.
I take this opportunity to thank my friends and parents who have imparted their knowledge in a friendly and loving manner, and the librarian of the University, without whom this project would not have been materialised.
My gratitude also goes to http://www.ecs.csun.edu/shustov/Topic4.htm, and http://www.architectjaved.com/earthquake_resistant_structures/base_isolation_techniques_for_earthquake_resistance.html, from where I took the required data for reference during the course of my work.
Base isolation which is also known as seismic or base isolation system is nothing but an accumulation of structural constituents which considerably dissociates the main structure from the damaging components of the earthquake. This prevents the main structure from absorbing the earthquake energy. The total superstructure must be defended on separate isolators whose vibrant characteristics are selected to separate the ground motion. Some isolators are also intended to add considerable damping. Dislocation and compliant are determined at the point of the isolation devices, and the superstructure. Base isolation for earthquake protection was first used in Pasargadae which is a city in antediluvian Persia and dates back to the VI century BC.
1.2 WHAT IS BASE ISOLATION
Base isolation is the most powerful tool of earthquake engineering when it comes to the aspect of controlling the shakiness of a structure and the technology used for it. It is intended to enable a building or non-building structure to come through a
