  • An Earthquake Response Analysis of Partially Concrete-filled Steel Column with Considering Debond

抄録

In this paper, a series of dynamic analyses is made on a partially concrete-filled steel box column, with considering the debond of the steel concrete interface. The numerical model of the column, in which the local buckling of the steel plate shall be preceded, is adopted in the analyses, because the out-of-plane deformation of the plate due to debond is considered to accelenate the local buckling of the plate. The analyses are made under two types of the seismic motions observed in the Chuetsu Earthquake in 2004; one is the main shock with the maximum ground motion of 1675.8 gal, and another one is the largest aftershock with 2035.6 gal. Debond is practiced by using the "interface elements" provided in the computer program package LUSAS. The results of the analysis indicate that larger displacement is arisen by the main shock rather than the aftershock although the aftershock has the larger ground acceleration.
