내부구속중공 RC 기둥의 내부 구속력 연구

Abstract

Recently study of confining effect in column member is progressed. But these studies are limited to about RC column and external confining effect in hollow column. Internal confining effect in hollow column has not researched that generally assumed the same external confining effect. In this study there are to investigate the internal direction confining effect ICH RC columns. We performed parametric studies to find main parameters that affect the internal confining effect. Parametric study has performed using FEA program (ABAQUS) which parameters are hollow ratio, diameter of column.ally assumed the same external confining effect. In this study there are to investigate the internal direction confining effect ICH RC columns. We performed parametric studies to find main parameters that affect the internal confining effect. Parametric study has performed using FEA program (ABAQUS) which parameters are hollow ratio, diameter of column.
