Double-sided shear experimental study of bond-slip performance of aluminum alloy plate-concrete interface
Aluminum alloy plate has the advantages of high strength
good ductility
good corrosion resistance
which can be used to strengthen concrete structures in damp
cold and harsh environments. However
the interface performance of aluminum alloy plate-concrete is the key factor which affect the effect of concrete reinforced by aluminum alloy plate. Based on this
the interfacial double shear tests of 48 aluminum alloy plate-concrete specimens were completed. The influence of bond thickness of aluminum alloy plate
bond length of aluminum alloy plate and structural adhesive type on the interface failure mechanism
interfacial peeling bearing capacity
bond shear stress and the slip evolution were analyzed. The results show that the peeling capacity of the interface can be effectively improved by increasing the thickness of the aluminum alloy plate
the bonding length of the aluminum alloy plate and using the structural adhesive with low elastic modulus
but the bonding length of the aluminum alloy plate should be controlled within the range of the limited bonding length. At the same time
with the increase of bond length
the slip of specimen increases
and the thicker the bond thickness of aluminum plate
the lower the slip of the specimen. Use double-line model
hyperbolic model
Nakaba model and test results for comparative analysis. The results show that the aluminum alloy plate-concrete bond slip is in good agreement with the curve of the Nakaba model.
