    In this study, shear tests were conducted to investigate the effects of longitudinal reinforcement corrosion on the shear capacity of reinforced concrete (RC) members with transverse reinforcement. To this end, a total of eight test specimens were fabricated, and the corrosion rates and anchorage details of rebars were set as test variables. In addition, an accelerated corrosion technique was Cited by: 3. Title: Concrete Shear Strength: Another Perspective Author(s): A. Koray Tureyen and Robert J.

Date: 9/1/ Abstract: Recent tests of beams reinforced with fiber-reinforced polymer (FRP) bars indicate that.

    Experimental results show that concrete shear walls reinforced with a hybrid scheme of steel and fiber-reinforced polymer (FRP) bars are able to achieve similar strength, stiffness and ductility. Design Example 2 Reinforced Concrete Wall with Coupling Beams OVERVIEW The structure in this design example is a six-story office building with reinforced concrete walls as its seismic-force-resisting system. The example focuses on the design and detailing of one of the reinforced concrete walls.

      AbstractSafe and economical design and assessment of reinforced (RC) including more than 1, tests on RC and PC beams with and without stirrups, has been observed.

First results of the use of rectangular spiral reinforcement in shear-critical RC beams with rectangular cross-section have been reported by Karayannis et al., whereas Yang et al. examined the shear behaviour of concrete T-beams that have been reinforced using spiral-type wire rope as internal shear by: Tests of shear-critical RC beams with rectangular spirals as shear reinforcement.

Advanced continuous rectangular spiral with shear-favourably inclined vertical legs. The use of spiral reinforcement provided enhanced shear capacity and by:   The beams were tested with one or two concentrated loads and all failed in shear after one or more diagonal tension cracks formed in the region of maxi-mum shear.

The magnitude of the loading causing the initial diagonal tension cracks depended primarily on the cross section and the concrete by:   This paper summarizes all available previous shear tests on fiber reinforced concrete beams without stirrups, and presents the results from 11 large-scale beam element tests.

The beams had an overall depth of mm (effective depth of mm), and were constructed with varying amounts of hooked steel fibers (0 to percent by volume).Cited by:   Twenty singly reinforced high strength concrete beams without web reinforcement were tested to investigate their behaviour and to determine their ultimate shear capacities.

Test variables were longitudinal steel ratio (ρ), shear span to depth ratio (a/d) and effective depth (d).Cited by: In this paper testing of eighteen reinforced concrete beams without shear reinforcement is compared to three building codes; American Concrete Institution Building Code Requirements for Structural.

Numerous investigations of RC beams strengthened in shear with externally-bonded (EB) fibre-reinforced polymer (FRP) sheets, plates and strips have been successfully conducted in recent years. These valuable studies have highlighted a number of influencing parameters that are not captured by the design guidelines.

The objective of this study was: (1) to highlight experimentally and Cited by: CIVL Shear CRITERIA FOR FORMATION OF DIAGONAL CRACKS IN CONCRETE BEAMS v ave = V bd ♦can be regarded as rough measure of stress ♦Distribution of “V” is not known exactly, as reinforced concrete is non-homogeneous.

Four reinforced concrete beams were cast and tested in shear; see Fig. One beam (B1) was un-strengthened, and was used as a control beam. The remaining three beams B2, B3 and B4 were strengthened for shear using NSM by: To investigate the shear strength and behavior of concrete beams reinforced with fiber-reinforced polymer (FRP) bars, nine large- Shear Tests of FRP-Reinforced Concrete Beams without Stirrups.

In this study, shear tests were conducted to investigate the effect of corrosion damage induced in longitudinal reinforcement on the shear resistance mechanisms of reinforced concrete (RC) members without transverse : Sun‐Jin Han, Deuckhang Lee, Seong‐Tae Yi, Kang Su Kim.

Test results indicate that the fibers have significant influence on the mode of failure and ultimate shear strength of a longitudinally reinforced concrete beam. Conventional reinforced concrete analyses with some modification, as suggested in this paper, to account for the effect of fibers give good predictions of the ultimate strength and the mode of failure for rectangular beams with no shear reinforcement.

Results of tests on 52 deep reinforced concrete beams under two equal symmetrically placed point loads are reported. The investigation’s objectives were to study the effect of vertical and horizontal web reinforcement and shear span-to-effective depth ratio on inclined cracking shear, ultimate shear strength, midspan deflection, tension Cited by: Shear Strength of Reinforced Concrete Beams per ACI Course Content 1.

Introduction In a simple beam subjected to bending, the fibers above the neutral axis are in compression, whereas tensile stresses occur in the fibers below this axis. The factors influencing shear strength and formation of inclined cracks areFile Size: KB.

Introduction. The shear behaviour of deep reinforced concrete beams has been a subject of intensive experimental studies since the s. It has long been recognized that, due to their small shear-span-to-depth ratios (a/d ⩽ approx.
