Abstract: Anchor-bolt-yield-type exposed column-bases exhibit slip-type restoring force characteristics. The authors had proposed non-slip-type column-bases that use a wedge device to minimize slip. This paper clarifies the self-centering capability and cumulative damage response of a portal frame and a 4-story frame with non-slip-type and slip-type exposed column-bases by time-domain analysis. The results show that the residual story drifts and cumulative damage response of second-floor beams for frames with non-slip-t… Show more

Anchor-bolt-yield-exposed-column-bases show various restoring force characteristics, that maximum bending moments fluctuate due to axial forces, especially variable axial forces including tension causing many resisting mechanisms. The column-bases with multi-rows of anchor-bolts generally used show multi-linear cyclic curves. The column-bases with anchor-bolts on the centroid axis show discontinuous slip-type cyclic-curves.In this paper, an experimental study on multi-rows of anchor-bolts column bases subjected to variable axial forces including tension and cyclic bending moment were carried out and the experimental results were examined to clarify the resisting behavior of the column bases.
