| Outline of Final Research Achievements |
Experimental study of square CFT columns subjected to axial load and cyclic lateral load was carried out. Test specimens were square CFT column with normal strength steel tube (STKR 400) and high strength steel tube (H-SA700). Test parameters are axial load ratio (ratio of the axial force to the compressive strength), the presence or absence of infilled concrete.
Limit rotational angles are shown obtained by the test results. Local buckling limit angle of the CFT column with high strength steel tube obtained by the test results and past experimental studies were compared with those of the CFT column with normal strength steel tube. Local buckling limit angle of the circular CFT column with high strength steel tube are greater than those of the CFT column with normal strength steel tube. However, when the cross section is square, local buckling limit angle of the CFT column with high strength steel tube are not always greater than those of the CFT column with normal strength steel tube.
