A macro-element model is developed to account for shear deformation and bon
d slip of reinforcement bars in the beam-column joint region of reinforced
concrete structures. The joint region is idealized by two springs in series
, one representing shear deformation and the other representing bond slip.
The softened truss model theory is adopted to establish the shear force-she
ar deformation relationship and to determine the shear capacity of the join
t. A detailed model for the bond slip of the reinforcing bars at the beam-c
olumn interface is presented. The proposed macro-element model of the joint
is validated using available experimental data on beam-column connections
representing exterior joints in ductile and nonductile frames.
