| Research Abstract |
In Japan, we started to study soil-pile-structure interaction problems about 30 years ago, but very few structural engineers considered lateral forces to design piles supporting building structures at that time. During the Niigata Earthquake (1964), Miyagiken-oki Earthquake(1978), Hyogoken-nanbu Earthquake (1995) and other large earthquakes, many piles were damaged severely and many buildings on these piles were inclined after the earthquake. In the last 20 years, many engineers have come to consider the behavior of soil-pile-structure interaction. The piles have to support the gravity weight of the building and will be subject to the lateral force caused by the earthquake. Very strong piles are needed for these two large forces. In this study, we use two groups of piles supporting the building. The first group has long-flexible-piles for the building gravity weight, and the second group has short-stiff-piles resisting the lateral forces due to earthquake ground motion. We will present the basic idea and the results of a small shaking table test of soil-pile-structure interaction problems for our new idea.
