Abstract In a context where daily and seasonal temperature changes or potential fire exposure can affect the mechanical response of structures strengthened with fiber-reinforced polymer (FRP) composites during their life cycle, present work studies bond behavior FRP laminates glued to concrete substrates under thermal variation. The problem is tackled computationally by means contact algorithm ...

Over the world, there is growing worry about corrosion of reinforced concrete structures. Structure repair, rehabilitation, replacement, and new structures all require cost-effective long-lasting technologies. Fiber Reinforced Polymer (FRP) has been widely employed in both retrofitting existing building ones. Due to its varied qualities masonry constructions as a repair composite material, FRP ...

We observe that the known fact that difference logic and hybrid logic with universal modality have the same expressive power on Kripke frames can be strengthened for a far wider class of general frames. This observation, together with a general completeness result, is used to show that lattices of difference logics and of hybrid logics are isomorphic.

This article proposes an alternative method for the structural design of reinforced concrete elements strengthened in bending by metallic plates or fiber-reinforced polymer (FRP) bonded to substrate. It is proposed a new calculation procedure strengthening using thin adhered material element surface that dispenses iterative process generally used design. The routine validated comparison with ot...

There is growing use of FRP composite materials in the civil infrastructure for rehabilitation of deficient bridge components including deck slabs and girders. However assessment of the effectiveness of rehabilitation over time and monitoring the progression of damage or change in load paths between the structural components, caused by sequential strengthening of the components, has not been un...

Nanomaterials have been used in improving the performance of construction materials due to their compacting micro-structure effect and accelerating cement hydration reaction. Considering brittle characteristic fiber reinforced polymer (termed as FRP) tube encased concrete inferior properties recycled concrete, nanoparticles were FRP aggregate concrete. The axial compressive treated with strengt...

Abstract In reinforced concrete (RC) structures, corbels that extend from the faces of columns are commonly employed to support primary beams and girders. Frequently, use is limited cantilevers with a shear span-depth ratio often less than 2. Because this relatively low ratio, corbel strength normally dominated by shear, which comparable deep beams. However, owing some reasons (e.g., design and...

Existing buildings are retrofitted to formulate them be more resistant seismic activity, earth motion, and other natural disasters. Many available reinforced concrete across the globe in desperate need of rehabilitation, repair, or replacement owing degradation caused by a variety reasons such as corrosion, lack detailing, failure beam-column bonding, among others. In construction sector, fibre...
