Behaviour of concrete-filled steel columns under the seismic loading
AbstractThis paper describes results of a dynamic analysis on partially concrete-filled steel columns, which are used for piers of the motorway viaduct. As a seismic loading the ground motion measured in the main shock and one of the post shocks of Chuetsu earthquake in 2004 are used. These two shocks have different vibration patterns and therefore the influence of the vibration pattern of the seismic load can be investigated. Through the analysis it is found that the main shock, which has smaller ground acceleration than the post shock, causes a larger displacement of the column because the frequency component of the main shock is similar to the natural frequency of the column.
