STUDY ON INFLUENCE OF HYSTERETIC CHARACTERISTICS OF SPRING MODEL OF SOIL AND TYPES OF CONNECTION CONDITION AT PILE HEADS TO EARTHQUAKE RESPONSE OF SUPERSTRUCTURES

Abstract

Recently, a lot of research works on the base structures have been conducted. For example, the research on the influence of the connection conditions at piles heads on the seismic response of superstructures is one of a major theme of these researches. However, ground conditions are limited and the peeling between soil and piles which occur during earthquakes was not considered in these researches. This paper studied the seismic response of superstructures considering the various ground conditions and peeling. As a result, the influence of the peeling on the response was found to be remarkable particularly when superstructures are elastic.
