Abstract
In order to clarify restoring force and deformation characteristics of reinforced concrete (RC) pile – soil system, static and dynamic loading tests were conducted for RC piles in dry sandy soil. It was clarified that, within the range of the tests, the restoring force at pile head can be determined from the maximum damaged depth of the pile which depends on the relative stiffness between the pile and its surrounding soil. Additionally, it was observed in the dynamic loading tests that the loading velocity has a small effect on the restoring force of the pile. The derived results from these tests can be used to establish an accurate evaluation method for seismic performance of RC structures.
Key words: Dynamic and static analysis, reinforced concrete piles, dry sand, restoring force.
