Corrosion of steel reinforcement is the major cause deterioration in reinforced concrete structures. Strengthening structures has been widely studied. However, most research was conducted on sound without considering effects corrosion. This paper presents an experimental study feasibility using externally bonded FRP laminates combined with U-jackets, applied directly repairing deteriorated cove...

In this study, an experimental program was developed to investigate the flexural behavior of pre-damaged reinforced concrete (RC) beams that had been repaired and strengthened using carbon fiber-reinforced polymer (CFRP) laminates under a monotonic load. Two techniques were used: externally bonded reinforcement (EBR) near-surface-mounted (NSM) reinforcement, repair strengthen tested beams. The ...

The fire resistance of reinforced concrete (RC) beams strengthened with externally bonded reinforcement carbon fibre-reinforced polymers (EBR CFRP) depends on the load level and degree strengthening. Design guides for this type structure recommend strengthening limits to prevent collapse due vandalism, damage or fire. In practice, however, it is not uncommon exceed proposed limits. This necessi...

When rubberized, concrete beams lose some of their flexural strength. Conversely, strengthening accounts for a sizeable portion the structural applications external carbon fiber reinforced polymers (CFRP) sheets that strengthen beams. In this study, externally bonded were used to compensate strength loss brought on by using rubberized in constructing The study's split into two groups, each with...

Rebar fracture in boundary elements of lightly reinforced shear walls in recent earthquake motivated research on the minimum longitudinal reinforcement applicable to shear walls. These researches lead to change in the ACI 318-19 requirement for minimum longitudinal reinforcement in boundary elements. New ACI 318 requirement increase minimum longitudinal reinforcement ratio for boundary elements...
