Study on Shear Strength of SRC Beam-Column Connections
This paper proposes a new model to predict the horizontal shear strength of SRC, especially SRHC/SRUHC, beam-column connections on the basics of previous models developed for RC and RCS connections. The model divides the contributions to shear strength of a connection into three parts, the contribution of steel web, inner strut and outer strut. The predicted values coincide with experiment results very well, which proves that the model is suitable for SRC connections. It is found that the inner strut plays a dominant role in the strength mechanisms in SRC joints, so adequate web stiffeners in joints should be provided. It is the stirrups in a joint, rather than concrete strut, that usually determine how much contribution the outer strut mechanism provides to the joint.
