| الوصف: | Structural Faults and Repair 2016, Edinburg, ROYAUME-UNI, 17-/05/2016 - 19/05/2016; Externally bonded composite reinforcements have proven their efficiency in the strengthening of existing concrete structures. Regarding their use in the case of old steel structures, there is however much less literature, more particularly concerning their use for old steel materials such as puddled iron and mild steel. In the case of steel structures, the adhesive joint behaviour becomes more tremendous than in the case of concrete, as it will be the weak link of the assembly. That's the reason why we decided to investigate the bond behaviour between CFRP (Carbon Fiber Reinforced Polymer) laminates and different old steel materials (mild steel and puddled iron). Different commercial reinforcement processes (different composite elastic modulus and thicknesses, different adhesives) have been experimentally studied investigating the materials' behaviour (steel, and adhesive) and the assembly behaviour through the realization of single lap shear tests. Some of the shear samples were monitored using strain gages during the test in order to determine an equivalent interfacial behaviour that may be used during the design process of the reinforcement. Additionally, some load/unload cycles have been applied to check their effect on the assembly capacity. |
