Shear capacity of RC members without shear reinforcement: A modified crack sliding model

The influence of small amounts of shear reinforcement on the shear‐transferring mechanisms in RC beams: An analysis based on refined experimental measurements

“…In the following, the experimental programme and the results are briefly described. For a thorough description of the experiments, the reader is referred to Autrup et al 4 . Figure 2 shows the test setup and details of the beams.…”

“…In this paper, a detailed investigation of the influence of shear reinforcement on the shear behavior of five representative beams from Autrup et al 4 is presented. The investigation shows that the crack development at the ultimate load is more severe for beams with a small 0 0.5 F I G U R E 1 Tested shear capacities for varying (a) shear reinforcement ratio, ρ w , and (b) distance between stirrups, s, from Autrup et al 4 amount of shear reinforcement, compared to beams without shear reinforcement. Additionally, based on the measured crack kinematics, the well-known constitutive model by Walraven, 14,15 is applied to estimate the contribution from aggregate interlock.…”

Carbon reduction and strength enhancement in functionally graded reinforced concrete beams

“…Thirdly, these shear failures are mainly governed by the properties of the concrete, rather than those of the reinforcing steel so functional grading holds promise. Finally, according to recent theories of shear in concrete, failure is associated with critical shear cracks [6,[17][18][19][20]. This suggests that performance enhancement might be obtained if material changes artificially modify the propagation of cracks in plain concrete.…”

Arch action in reinforced concrete subjected to shear

“…It was recognised that beams were able to withstand significant loads even after the appearance of dominant cracks, and this led to the development of shear-friction theories that focussed on the contribution of aggregate interlock [46][47][48][49][50][51]. Recent approaches attribute the ultimate shear resistance to the load transfer across a critical crack and its kinematics [3,14,[52][53][54][55][56][57][58][59], although simplifications are necessary because the exact shape and position of the critical cracks are believed to be unpredictable. The relevance of aggregate interlock is not recognised in the theory of the Compressive Force Path (CFP) [18,26,30] which has commonalities with Kani's theory and truss analogies but gives a different interpretation to shear failure.…”
