“…4) and defines the calculations to be performed to determine the reinforcement required for each of them. The design equations are based on the studies of Mattock and Chan [4] and are suitable for short dapped ends (a/d 6 1), where a is the shear span and d is the effective depth of the dapped end. The main modes of failure to be considered are characterized by cracks 1-5 in Fig.…”

“…An analytical model for determining the shear strength of reinforced concrete dapped-end beams is also proposed. Both the shear strengths predicted by the proposed model and the approach of the PCI Design Handbook are compared with test results of this study and those of Mattock and Chan (1979). The comparison shows that the proposed model can predict the shear strength of reinforced concrete dapped-end beams more accurately than the approach of the PCI Design Handbook.…”

In this study, 12 high-strength concrete dapped-end beams were tested to study the effects on shear strength of dapped-end beams of the concrete strength, the amount of main dapped-end reinforcement, and the nominal shear span-to-depth ratio. The test results indicate that the shear strength of dapped-end beams increases with the increase of the concrete strength, the amount of main dapped-end reinforcement, and the decrease of nominal shear span-to-depth ratio. An analytical model for determining the shear strength of reinforced concrete dapped-end beams is also proposed. Both the shear strengths predicted by the proposed model and the approach of the PCI Design Handbook are compared with test results of this study and those of Mattock and Chan (1979). The comparison shows that the proposed model can predict the shear strength of reinforced concrete dapped-end beams more accurately than the approach of the PCI Design Handbook.

“…Lu et al 2 concluded that the shear capacity of dapped-end beams increased with the decrease of effective shear span-to-depth ratio of nib, and increase of nib longitudinal reinforcement and concrete strength. On the other hand, Mattock and Chan 3 showed that dapped-end beams exhibited different failure modes with the variation of nib shear span-to-depth ratio and amount of reinforcement at different locations.…”

1 SHEAR STRENGTH OF REINFORCED CONCRETE DAPPED-END BEAMS USING MECHANISM ANALYSIS ABSTRACTA mechanism analysis based on upper-bound theorem of concrete plasticity is developed to predict the critical failure plane and corresponding shear capacity of reinforced concrete dapped-end beams.Failure modes observed in physical tests of reinforced concrete dapped-end beams are idealized as an assemblage of two moving blocks separated by failure surface of displacement discontinuity. The developed mechanism analysis rationally represents the effect of different parameters on failure modes; as a result, the predicted shear capacity is in good agreement with test results. On the other hand, empirical equations specified in PCI design method and strut-and-tie model based on ACI 318-05 highly underestimate test results. The shear capacity of dapped-end beams predicted by the mechanism analysis and strut-and-tie model decreases with the increase of shear span-to-full beam depth ratio when failure occurs along diagonal cracks originating at the bottom corner of beam full depth, though the shear span-to-full beam depth ratio is ignored in PCI design method.
