Recently, composite structural systems have been developed actively due to its structural advantages of combining different
materials. The purpose of this experimental study is to evaluate the structural performance of RCS structures. Six specimens
were manufactured in 2/3 scale and the stress transfer mechanisms in the RCS joint were investigated. The specimens include
one standard type (LCS) and five cover plate types (LCC series). The standard type specimen uses transverse tie bars in the
joint for the joint confinement and the shear resistance. The specimens in LCC series were designed with cover plates on the
joint instead of transverse reinforcements of LCS specimen. Experimental variables of LCC series are joint details of an
artificial hole in steel web, low strength of concrete, cover plates not welded together, beam failure type instead of the joint.
Overall response of all the specimens is satisfactory in terms of stiffness retention capacity, joint shear resistance although
they were designed to fail in the joint. The cover plates are found to confine the joint effectively providing high capability of
joint shear resistance. The hole in steel web panel did not reduce the joint shear strength. However, full confining effect cannot
be expected if cover plates are not welded together. In addition, the predictions by ASCE guidelines showed that the joint
strength might be estimated conservatively.
