RELATION BETWEEN EXPERIENCED LATERAL DRIFT ANGLE AND RESIDUAL ONE OF CONCRETE FILLED STEEL CIRCULAR TUBULAR COLUMNS

摘要

Relation between experienced lateral drift angle and residual one of concrete filled steel tubular columns were discussed with data obtained from the experimental work of circular CFT columns which had been already carried out. And relation between residual lateral drift angle and critical rotation angle was discussed. This paper showed the effect of axial force ratio and width-thickness ratio on residual lateral drift angle.
