Abstract:
Retrofitting of slab-column connections has become a crucial concern as they are highly
vulnerable to fail in punching shear failure. External strengthening is practically feasible
rather than the post-installation of shear reinforcement in deteriorated slab-column
connections. Hence, the behavior of medium scale slab-column junctions strengthened
with alternative arrangements of Carbon Fiber Reinforced Polymer (CFRP) was studied.
Numerical models were also developed to analyze bond behavior. The model predicted
performances are in good agreement with the test results. The maximum average punching
shear enhancement of 46% was observed from the specimens with CFRP plates attached to
the tension face of the specimens with steel end anchors.
