Shear strengthening of reinforced concrete beams with CFRP

The current paper reviews existing design guidelines for strengthening beams in shear with carbon fibre reinforced polymer (CFRP) sheets and proposes a modification to Concrete Society Technical Report TR55. It goes on to present the results of an experimental programme which evaluated the contribution of CFRP sheets towards the shear strength of continuous reinforced concrete (RC) beams. A tot...

FRP Shear Reinforcement for Concrete Structures

Shear Area of Reinforced Concrete Circular Cross-section Members

The shear strength of reinforced concrete members without shear reinforcement is related to the shear stress carried by the concrete effective shear area. For rectangular sections the effective shear area represents the area corresponding to the effective depth. However, for circular sections this area is not as readily defined. Different empirical proposals have been suggested recently but no ...

Shear strength model of reinforced concrete circular cross-section members

A shear capacity model of reinforced concrete members with circular cross section transversely reinforced with circular hoops has been developed. The proposed model is based on the truss analogy by adding a concrete contribution term to the capacity of the shear reinforcement. An additional deviatoric shear resisting th c curv pres nism ste ved und ctor mechanism of hoops present solely in memb...
