Analytical behaviour of FRP strengthened reinforced concrete beams under low velocity impact load incorporating rate dependant material constitutive models
Since the 1980s, the use of fibre reinforced polymer (FRP) composites in strengthening and rehabilitation of existing reinforced and pre-stressed structures has gained popularity. Versatility, high strength to weight ratio, corrosion resistance, excellent creep and fatigue behaviour, and ease of …

STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues
… the behaviour of beams retrofitted with fibre reinforced polymer (FRP). The ABAQUS program was used for this purpose. Concrete was modelled using a plastic damage model. Steel bars were modelled as an elastic perfectly plastic material, with perfect bond between concrete and steel. A …

Behaviour of Fibre Reinforced Polymer Confined Reinforced Concrete Columns Under Fire Condition
In recent years, fibre reinforced polymer (FRP) materials have demonstrated enormous potential as materials for repairing and retrofitting concrete bridges that have deteriorated from factors such as electro-chemical corrosion and increased load requirements. However, concerns associated with fire …

Strengthening of RC slabs with penetrations using unanchored and anchored FRP composites
Reinforced concrete (RC) slabs are one of the most commonly occurring structural forms. Penetrations (otherwise known as openings or cut-outs) in new as well as existing concrete slabs are commonly introduced due to structural and/or functional reasons. The introduction of a penetration, if large …

Effect of concrete heterogeneity on FRP-to-concrete bond behaviour
Fibre reinforced polymers (FRP) are widely used for strengthening or retrofitting deteriorated structures, due to their various advantages. In FRP-strengthened concrete structure, one of the main failure modes is the premature bond failure, which prevents the exploitation of the full capacity of …

Nonlinear Finite Element Analysis of FRP Strengthened RC Beams under Static and Cyclic Loads
Fibre reinforced Polymers (FRPs) are being used increasingly in enhancing reinforced concrete structures in civil constructions due to their superior characteristics. A large number of experimental and numerical studies have been carried out on FRP strengthened RC beams in recent decades. However, …

Fatigue Behaviour of CFRP Strengthened Reinforced Concrete Beams
The performance of reinforced concrete (RC) structures, such as bridges in the heavy haul industry, may be severely impacted by fatigue when subjected to repeated cyclic loading. Fatigue not only reduces load carrying capacity and serviceability limit states (SLS), but it can cause structural …
