Abstract

This study aims to clarify the shear capacity of flanged L-shaped RC members. Three specific tests with a total of nine flanged L-shaped RC beams were carried out under four point bending conditions to investigate the influence of the shear reinforcing ratio (rw) and the shear span ratio (a/d). The results show that the actual shear capacity of flanged L-shaped RC beams is at least 1.54 times larger than that calculated conventionally because a large number of stirrups support the shear force. Finally, based on the actual crack distribution, a two line model and a three line model for predicting the actual shear capacity of flanged L-shaped RC beams are presented.
