The seismic design codes for concrete structures were revised in several organizations after Hyogo-ken Nanbu earthquake. To aim at a performance based seismic design for reinforced concrete columns, we proposed deformation limit points related to damage levels taking restorability into account and a method of evaluating the deformation capacity of each limit point.
In this paper, deformation limit points of the cast-in-place reinforced concrete pile are defined and a method of evaluating the deformation capacity of each limit point in consideration of the section shape, the construction condition and the axial load is proposed based on the method for reinforced concrete columns.
