PDF Shear Resistance of Reinforced Concrete Beams Without Stirrups

Six series of beams were cast, three of each series, a total of eighteen beams. They were reinforced in the tensile area but not for shear. The variables were two; beams of different height (105mm - 335mm) and reinforcing steel percentage (1.31% - 1.55%). My findings were that the ACI-318 code gives a very conservative conclusion. The

Strengthening of Reinforced Concrete Beam (RC Beam) | Methods

Strengthening of RCC beams. The need for strengthening a reinforced concrete beam or a number of beams in a structure is usually caused by problems due to degradation of characteristics of materials with time, reduction in cross section, corrosion, wrong initial design or the increase in the load demand on the building when its utilized for a new purpose other than it was intended to.

Deep Beam - Angelfire

R. Narayanan and I.Y.S. Darwish (1988) [4] reported the results of tests on twelve reinforced concrete deep beams including eleven containing steel fibers, provided to act as web reinforcement. Three parameters were varied in the study, namely, the volume fraction of fibers, shear span-to-depth ratio and the concrete compressive strength.

NJIT ETD: "Shear behavior of reinforced concrete deep

However, very few tests have been performed on reinforced concrete deep beams with CFRP as shear reinforcement. The purpose of this experiment is to investigate the behavior of the deep beam in shear with various arrangements of Sika CarboDur laminates bonded to the sides.

Strut Efficiency-Based Design for Concrete Deep Beams

Therefore, our study aimed at developing a new STM based on the tested FRP-reinforced concrete deep beams. Concrete deep beams have relatively small span-to-depth ratios, so that shear

show stress ranges for which design requirements change. No shear reinforcement (stirrups) are required if Vn/(bwd) is less than 1.0√fc'. The capacity Vc of concrete in sections reinforced for shear is 2.0bwd√fc'. The strength of stirrups can be added to the concrete strength Vc to determine the total strength of a section.
