Abstract
Recently, study of confining effect in column members is progressed. But these studies are limited to about RC column and external confining effect in hollow columns. Internal confining effect in hollow columns has not researched. Internal confining stress is assumed the same external confining stress in hollow columns. In this study, there are to investigate the internal direction confining effect in ICH CFT column by FEA analysis. FEA analysis methods have verified by experimental values. Parametric study has performed as thickness of internal tube, hollow ratio, diameter of column and bending stiffness between concrete and external tube. Modified equations have suggested to estimating economic and reasonable thickness of internal tube.
