Secondly, the shear strengths of corroded reinforced concrete beams are compared with those predictions obtained by other researchers. The effects of corroded stirrups on the shear resistance of reinforced concrete beams are also analysed. Generally, it is shown that the shear strength of beams ...
Synopsis: Synopsis: Synopsis: Synopsis: Synopsis: ACI Committee 440 has proposed a design approach for evaluating the concrete contribution to the shear resistance of FRP-reinforced concrete beams that accounts for the axial stiffness of FRP longitudinal reinforcement. Recent shear tests conducted on bea...
Aspects relating to codification of the in-plane shear strength of concrete masonry walls when subjected to seismic loading are presented in this paper. Particular emphasis is placed on a model that is capable of representing the interaction between flexural ductility and masonry shear strength to acc...
Most of these design provisions follow the traditional approach ofVc+Vsfor shear design. Nevertheless, both equations of concrete contributionVcand FRP stirrup contributionVsto shear strength in these guidelines are different in the manner that they are calculated. In this paper, five methods for ...
A design equation for shear strength is proposed upon investigation of published test results on shear strengths of reinforced concrete beams without web reinforcement. The proposed equation is deduced based on experiments of beams failing in a diagonal tension mode and subjected to no axial force, ...
Design methods for the shear resistance of reinforced and prestressed concrete beams are based on empirical evidence. Due to different approaches in their development different equations are used to calculate the shear strength of reinforced and prestressed concrete. Recent research conducted by Tureyen ...
This is due to insufficient amount of shear reinforcement, corrosion of existing shear reinforcement, low concrete strength and/or increased design load. Shear strengthening of RC beams with TRM jacketing has been investigated by several researchers in the last decade [1,[29], [30], [31], [...
For simplified shear design of slender reinforced concrete (RC) beams with stirrups, a modified variable-angle truss model is developed in this paper. In this model, an analytical solution of the inclination of struts (θ) is derived by combining the theory of plasticity and the concrete soften...

A mechanical model recently developed for the shear strength of slender reinforced concrete beams with and without shear reinforcement is presented and extended to elements with uniformly distributed loads, specially focusing on practical design and assessment in this paper. The shear strength is considere...
