Abstract
The structural method of semi-rigid pile head connection for cast-in-place concrete piles has been developed. By this method, it is possible to reduce the bending moment of pile head to about half as much as the case of the conventional method, and it has the deformation performance of greater than 3/100 radian. This paper presented the outline of loading tests of pile head connections, the proposal on evaluation method for structural characteristics of the semi-rigid pile head connection, and the trial calculation results applied for the pile foundation of the 15-story apartment building.
