This paper presents the shear performance of reinforced concrete (RC) beams with Tsection. Different configurations of externally bonded carbon fiber reinforced polymer (CFRP) sheets were used to strengthen the specimens in shear. The experimental program consisted of six full-scale, simply supported beams. One beam was used as a bench mark and five beams were strengthened using different confi...

The strengthening of concrete structures externally bonded with fiber reinforced polymer (FRP) sheet is increasingly being used for repair and rehabilitation of existing structures. This paper provides information in the area of long-term durability of FRP-concrete interface externally bonded with FRP composite sheet. It mainly discusses and summarizes the influence of harsh environmental expos...

This article investigates the potential detrimental effects of cyclic load during installation externally bonded (EB) carbon fiber-reinforced polymer (CFRP) on a damaged reinforced concrete (RC) structure. Four RC specimens were tested in three point bending to study consequences crack opening-closure epoxy-curing period. A first specimen (without CFRP) was loaded monotonically up failure serve...

• Self-anchored prestressed CFRP plates without the need for mechanical end anchorage. Significant improvement in bending stiffness, crack width, and load-carrying capacity. Nonlinear finite element analyses of flexural cracks crack-induced debonding plates. This paper presents an innovative method prestressing carbon fibre reinforced polymer (CFRP) used as externally bonded reinforcement stren...

This research program is intended to verify the influence of using distributed external U-wrap CFRP anchorage to shift the failure mode from overall debonding to sectional flexural failure for concrete beams externally bonded with CFRP sheets. Premature cover delamination and FRP debonding are predominant failure modes in FRP flexural strengthening that may be delayed or prevented by using FRP ...

limit to the tension reinforcement ratio ( ρ) in flexural high strength reinforced concrete (hsrc) members is based on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state. however, the provisions for the total amount of longitudinal reinforcement ratio ( ρ and ρ’) are not associated with any rational derivation. in this paper, a quantitative ...

In this paper, an innovative strengthening system for masonry walls made of externally bonded Fabric-Reinforced Cementitious Matrix (FRCM) is presented. Due to the good mechanical properties and compatibility with architectural heritage, FRCM adequate alternative use Fiber-Reinforced Polymer (FRP) composites other traditional techniques. The proposed applied a classical typology in cultural her...

Research on the use of CFRP materials for retrofit and strengthening of steel bridges and structures has increased in recent years. In order to implement these types of strengthening systems to longer span members, it is important to establish an effective method to splice adjacent lengths of CFRP laminates. This paper describes an experimental program to investigate the bond behavior of carbon...

Considering economical reasons and attempting to reduce carbon foot print of concrete structures, there is increasing tendency toward use of high strength reinforcement in seismically active regions. ACI 318-19, Iranian steel rebars standard INSO 3132 and next edition of Iranian national building allow the use of high strength rebars in elements of ductile force resisting systems. Therefore it ...
