The shear behavior of reinforced concrete beams has been a major research area depending on different factors that affect the shear response of reinforced concrete beams for a long time. Among the factors that affect the shear behavior of reinforced concrete beams,thearrangement,thespacingandtheamountofthestirrupwereexaminedinthis study. Furthermore, six specimens of cubes for the 7th and 28th days for the compressive strength test were prepared. And also, reinforced concrete beams, which have 150×150 mm cross-section and 750 mm length, with vertical, inclined, and combined stirrup arrangements were provided for the shear by keeping the constant grade of concrete and steel. Theinclinedandcombinedstirrupshad450 inclinationswiththeoppositedirection of the line of a possible crack in shear along with the supports on both sides. Mainly, this study focused on the shear capacity of the reinforced concrete beam with combined vertical-inclined stirrups. In experimental studies, eighteen (18) rectangular reinforced concretebeamshavebeentestedusingauniversaltestingmachine,whichhavetwopoints loading mechanism. The test results show that in the same spacing, the shear capacity of reinforced concrete beam with combined stirrup was increased by about 32.74% and 12.63% to conventional or vertical and inclined arrangement, respectively. And also, in case of the same amount of stirrup the shear capacity of reinforced concrete beam with combined stirrup was increased by about 25.4% and 14.96% to vertical and inclined arrangement respectively. Six (6) simply supported rectangular reinforced concrete beams was theoretically analyzed by the provision of ES EN- 1992-1-1:2015 and modeled on finiteelementsimulationsoftwarebyconstantmeshsizesandsimilarparametersasusedin the experiment for shear. A comparison of theoretical analysis, analytical finite element analysis software (ABAQUS), and the experimental results were done. Generally, the shear capacity of reinforced concrete beams was depending on the arrangement, spacing, and the amount of the stirrup. Finally, this study concluded that the combined stirrup is the optimal arrangement to keep the vertical alignment of the compression and tension face of longitudinal bar during installation and shear resistance capacity in both direct and reversed principal stress. The shear capacity ratio of experimental results to finite element method and ES EN-1992-1-1:2015 code provision results is within the range of 1.04to1.16and2.03to2.55respectively. Theshearcapacityofreinforcedconcretebeams obtained from finite element analysis is in a good agreement to experimental result on the other side ES EN- 1992-1-1:2015 has less value prediction.
