Abstract
This paper presents the experimental results of four lightly Reinforced
Concrete (RC) exterior beam-column joints with and without beam stubs under cyclic
loading with constant column axial force applied at the top of the column. The
parameter investigated was the type of reinforcement used in the beam, i.e. plain and
deformed bars. Test results showed that when the hooks anchored down in the column
increased the tensile stress in the diagonal concrete strut in the joint core, this led to
diagonal crack of the concrete and a decrease in the joint shear strength. The seismic
performance of the exterior RC joints without beam stub was also observed to be much
improved when the hook tail of beam reinforcements was bent inside the joint core.
The strut-and-tie model based on the recorded strain in the joint transverse
reinforcement could be used to determine the force flow in the joint core.
