Title: ANALYTICAL PREDICTION OF CONCRETE PILLARS SEISMIC RESPONSE WITH DIFFERENT LEVELS OF RESTRICTION IN THE HEAD.
Author(s): Luciano Roberto Fernández Sola, Gadiel Martínez Galindo.
Appears on pages(s): 2-17
Keywords: Kinematic interaction, restriction in the head, mechanical elements, dynamic interaction, soil structure.
Abstract:A parametric study about the distribution of flexural moments in concrete piles produced by kinematic interaction, due to seismic excitation is presented. In the study different levels of the pile head rotational restriction are considered. First, a parametric analysis of the rotational stiffness needed to produce a fixed head condition in the pile is developed. An equation to define this stiffness is proposed. In second place, the variation of the distribution and magnitude of flexural moment considering partially rotation at pile head is studied. It is shown that pile head moment keeps a relation with the restriction level. Finally, a comparison between numerical transient pile response and the proposed equations is presented.
