EVALUATION METHOD OF SHEAR CAPACITY OF RC REGION IN HYBRID BEAMS WHERE STEEL IS EMBEDDED IN RC REGION AT BEAM ENDS

Abstract

In recent years with the fabrication cost of steel soaring, there is a concerted effort to reduce the cost in order to construct large span buildings such as logistic terminals, shopping malls and medical facilities. Research investigations are being carried out and one of the methods is using a composite structure with reinforced concrete columns and hybrid beams. Since a greater shear force is transferred to the RC region, a precise method to estimate the shear capacity is necessary. Therefore, in this study hybrid beams under shear failure were examined and a method to the evaluate shear capacity is proposed.
