Shear strengthening of existing concrete bridges
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2003 The shear capacity of existing concrete bridge beams is often inadequate and unable to meet current code requirements. This is often due to increased traffic loads, inadequate shear-resistance provision in the original design or deterioration of materials due to aggressive environments.

Shear strengthening of beams with composite materials
, 2004 This paper presents the results of an experimental/analytical study aiming at obtaining a clear understanding of the underlying mechanisms of the shear strengthening of reinforced concrete beams with fibre reinforced polymers (FRP). Through the definition of the generalised constitutive law of a bonded FRP sheet, of the compatibility imposed by the ...

Shear Strengthening of RC Beams With FRP Composites
Structural Control and Health Monitoring, 2004 Shear strengthening is required when an RC beam is found deficient in shear, or when its shear capacity falls below its flexural capacity after flexural strengthening.

Buckling of Shear Loading Plates with Strengthenings
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000AbstractThe paper treats the influence of either weakening or strengthening of rectangular plates on the critical external buckling load. The plate geometry was chosen so that the buckling process takes place in the elastic range. The simply supported plate is loaded with shear forces per unit length which act on its edges.

Shear strength of strengthened RC beams with FRPs in shear
Construction and Building Materials, 2008Abstract We propose a predictive model for shear strength of RC beams strengthened by fiber material. It consists of a plasticity model for web crushing, a truss model for diagonal tension, and a simple flexural theory based on the ultimate strength method.

Shear Behavior of Strengthened Beams
2018Strengthening the reinforced concrete elements using polymer fibers continues to interest many researchers. In this context, an experimental study has been completed to evaluate the reinforcement on shear behavior of beams. Different fiber band positions were applied to beams in nodal zones. The four-point bending tests have been performed. The results

SHEAR STRENGTHENING OF URM CLAY WALLS WITH FRP SYSTEMS
Fibre-Reinforced Polymer Reinforcement for Concrete Structures, 2003This paper presents an experimental program dealing with the shear strengthening with FRP systems of URM walls built with concrete and clay units. Ten concrete and five clay masonry panels, strengthened with FRP composites in the form of laminates and rods, and stainless steel, were loaded along the wall diagonal to observe their shear performance. The

Shear Strengthening of Reinforced Concrete with CFRP
IABSE Congress Reports, 2000For about 10 years now, composite plates such as CFRP (Carbon Fibre Reinforced Plastic) have been state of the art for post-flexural strengthening of existing reinforced concrete structures. Thanks to a new innovation called 'L-shaped CFRP plates', it is now possible to shear-strengthen reinforced concrete structures.
