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.
This study is related to evaluate the performance of structural insulated panels. This panel plays a role as structural member and insulation simultaneously. This study is focused to test the racking shear capacity and axial compression capacity based on ASTM E-72 and KS F2273. The test result shows the panels are applicable to the required load sufficiently.
This study is related to evaluate the performance of structural insulated panels. This panel are composed of exterior structural member with insulated materials simultaneously. The test to evaluate the transverse capacity and lintel capacity was performed according to ASTM E-72 and KS F2273. The test result shows the panels are applicable to the required load sufficiently.
