In this paper, the static behavior of three dimensional cruciform structure using STKR column is investigated by the loading test. Parameters are the loading direction and the reinforced parts, an original specimen is not satisfied with the specification of column overdesign factor in the current seismic code. Test results show that the damage of each member of the original specimen is different by the loading direction, the column collapse easily occurs in case of 45 degree directional input. In case that the column is reinforced, the column collapse is prevented regardless on whether the panel is reinforced.
