A proposed column is an innovative steel integrated column by multiple steel pipes based on damage control design. This study shows that a difference of design condition affects seismic response by pushover analysis and dynamic analysis. We found that a cause-effect relationship between characteristic period of this column and response of spectrum property of seismic wave affects seismic response of this column. We also compared seismic response of single column with column with rahmen structure. The result shows that seismic performance of transverse direction with rahmen structure is same or more as that of the single column.
