In this study; In reinforced concrete cantilever beams, the effect of 20% iron chip additive and stirrup hook angle on the structural behavior of the cantilever beam was investigated. It has been investigated whether industrial iron chip waste, which will no longer be used and will be thrown into the nature, can be recycled by using it in the production of cantilever beams. Cantilever beams; By changing the diameters of the tensile bars, it is produced in two different ways as under-balance reinforcement and above-balance reinforcement. The amount of aggregates in the range of 0-4 mm in the concrete used in the production of cantilever beams was determined and this amount was reduced by 20% and cantilever beams with 20% iron chip were formed by replacing it with industrial waste material, iron chip. In each of the cantilever beams with under-balance and above-balance reinforcement, which are formed without and with additives; The stirrup hook angles were produced at 90 or 135 degrees, and a cantilever beam with two different stirrup types was formed. In this way, a total of 16 test samples were produced, two of each of the cantilever beams produced in 8 different types. Stirrup spacing of 100 mm was selected for all samples. In the experimental study, the load-displacement curves of the cantilever beams were obtained. Obtained results were compared and interpreted. According to this; In cantilever beams that do not contain additives, the ductility value of cantilever beams that are under-balance reinforced and whose stirrup hook angle is 135 degrees has increased by 3,20% compared to cantilever beams with 90 degrees, while this ratio is 7,26% for beams with above-balance reinforcement. In cantilever beams with 20% iron chip, the ductility value of cantilever beams with an angle of 135 degrees in the under-balance reinforcement increases by 6,93% compared to cantilever beams with 90 degrees, while it increases by 5,96% for beams with above balance reinforcement. In the under-balance reinforced condition, the ductility of the samples with 20% iron chip increased by 2,30% in samples with a 90 degrees stirrup hook angle compared to the samples without additive, while it increased by 6,00% in samples with a 135 degrees stirrup hook angle. In the above-balance reinforced condition, these ratios are calculated as 1,53% and 0,30%, respectively. The ductility coefficients of the samples created with under-balance reinforcement of the samples without additives with a 90 degrees hook angle increased by 9,88%, while the stirrups with a hook angle of 135 degrees increased by 5,71% compared to the samples created with above-balance reinforcement. For the samples with 20% iron chip, these rates were 10,70% and 11,72%, respectively.
