Earticle

초록

영어

Many piloti-type RC buildings were damaged by Pohang earthquake. It is necessary to reflect the characteristics of domestic buildings and failure mode by an earthquake to the post-earthquake safety evaluation criteria. In this study, the behavior characteristics and failure mode of RC walls of piloti-type buildings subjected to eccentric axial load was investigated by the reversal cyclic test. The variables were the aspect ratio(height to length) of the wall and the eccentricity which was different because the axial force was applied at the same position from the center of the wall specimens. As a result of the experiment, the slender wall was dominated by the flexure behavior. On the other hand, flexure-shear cracks occurred predominantly in the wall with a small aspect ratio. The crack patterns in the positive and negative loading directions were different due to the influence of eccentricity. The number of crack increased, and the rotation of the wall increased while the maximum horizontal strength decreased when the shear moment and the eccentric moment acted in the same direction by the eccentric axial force.
