Seismic Analysis and Reinforcement Details of Integral Pile Shaft-Column Foundations

말뚝-기둥 일체형 교각 기초의 내진해석 및 철근 상세

Integral pile shaft-column foundations are increasingly popular thanks to not only the comparative advantage of economy in constructing large cast-in-drilled-hole(CIDH) piles compared with driven piles with pile cap footings but also being free from problems associated with the critical column-footing connection. In this paper, the structural characteristics of integral pile shaft-column foundations as well as seismic analysis methodology and reinforcement details for seismic design are introduced.
