STUDY ON INFLUENCE OF TYPES OF CONNECTION CONDITION AT PILE HEADS TO EARTHQUAKE RESPONSE OF BUILDINGS

Abstract

Recently, the seismic performance of buildings with types of connection condition at pile heads has been studied widely. However, it has been difficult to evaluate the influence of the connection conditions at the pile head on the response of superstructures, because the seismic input is influenced by the connection condition at pile heads. The purpose of this study is to reveal how types of the connection condition at pile heads affect responses of superstructures under the investigation from the viewpoint of seismic energy. The result of the analyses shows that the response of elastic superstructures depended on types of the connection condition at pile heads. But if the superstructures standing on well foundation soils have been yield, they have little effect on the seismic performance of superstructures.
