h] is cross-sectional area of secondary reinforcement, distributed within the upper 2/3 of the corbel depth.
Concrete corbels containing neither primary nor secondary reinforcement failed in brittle manner with a noticeable difference in ultimate load.
It is clear from the results given in Table 6 that the primary and secondary reinforcement ratios increase as only the vertical load is increased.
1) The failure mode of corbels with neither secondary reinforcement nor primary reinforcement was brittle and explosive when corbel was subjected to only vertical loading;
The enhancement is noticeable until the percentage of secondary reinforcement reached to 0.
4) The PCI equations do not specify any limits on the ratio of primary and secondary reinforcement.
