STRENGTH OF SMALL SIZE STEEL ENCASED REINFORCED CONCRETE COLUMNS WITH HIGH STRENGTH MATERIALS

Abstract

This paper discusses the strength of a new SRC column. The SRC column is small size steel encased reinforced concrete column using high strength concrete and high strength hoop reinforcements. This SRC column is developed in order to have much higher shear strength than that of a reinforced concrete column. Seven SRC column specimens were made and tested. The concrete section of the specimen was 20cm×20cm, the steel section 10cm×5cm×0.5cm×0.7cm. Each specimen was diagonally compressed and consequently subjected to axial force, bending moment and shearing force. Experimental results indicate that high strength concrete and high strength hoop reinforcements function effectively. In this SRC column, it is negligible that the concrete section is separated by the steel.
