“…The dilation angles (ψ) may vary between ψ = 10° for RC corbels [26] to ψ = 40° for RC flat slabs [27,28] as a function of the structural configuration and modes of failure investigated. In this study, as illustrated in Figure 7b, a variation of ψ between 10° and 55°, shows that the best estimates for both peak strength and deformational behaviour are obtained for a dilation angle of ψ = 25°.…”

“…Furthermore, vertical failure force was increased by 50% and ductility of RC corbels was improved by the presence of horizontal stirrups. Besides, the elasto-plastic model had the most satisfactory accommodation with corresponding simulated geometry of the localized zones [15]. Afterwards, Rezaei et al in 2013 studied about normalstrength concrete corbels with 30 FE models, which were different in terms of various parameters, such as ratios of primary and secondary reinforcement and type of the applied loading (vertical or horizontal).…”

Reinforced concrete short corbels are widely used in engineering structures, such as bridges and precast structures. Therefore, the present comparative study was conducted on the structural behavior of the reinforced concrete corbels strengthened with carbon fiber-reinforced polymer (CFRP) laminates. For this purpose, numerical analysis was done using the finite element method. Therefore, nine models consisting of eight corbels strengthened with different CFRP arrangements in addition to an unstrengthened model were studied. The maximum load capacity, stiffness, ductility, and amount of absorbed energy were compared. In one of the above structure models, an innovative hunch was added at the top side of the corbel to column connection to investigate the differences with ordinary types of connections. Results revealed that the model used three bonded CFRP laminates all around the column and outside edges showed an 81% increase in loading capacity. Moreover, the corbel equipped with hunches had an 8% increase in stiffness compared to an ordinary corbel.

“…They proposed new material constitutive relationships by means of a regression analysis of experimental data, which were employed to formulate the material finite element (FE) models. Later, more sophisticated FE models for reinforced concrete corbels were developed (Abdul-Razzak, Mohammed Ali 2011b; Syroka et al 2011).…”

The study is concerned with normal-strength concrete corbels. 30 such corbels were studied by finite element modelling and the variables considered include ratios of primary and secondary reinforcement, type of applied loading, vertical or horizontal. Finite element modelling with a software package LUSAS was used to analyse four series of corbels namely PV series (primary reinforcement with vertical loading), SV series (secondary reinforcement with vertical loading), PH series (primary reinforcement with horizontal loading) and SH series (secondary reinforcement with horizontal loading).The results indicate that corbels with neither primary reinforcement nor secondary reinforcement fail suddenly. In the case of PV series and SV series, corbels increase in ratio of primary and secondary reinforcement generally resulted in enhancement of strength and ductility when subjected to only vertical loading. This increase is significant up to 0.4% in the case of primary reinforcement and 0.3% in the case of secondary reinforcements. No noticeable change in ultimate load or ductility was observed for corbels in PH series and SH series.
