Genetically compatible graphs for planetary gear train synthesis

Abstract

Reinforced concrete, RC beams subjected to shear failure which is the most unwanted failure mode due to speed progress is studied numerically. Therefore, the effective design of beams is necessary because of the sudden failure types of these beams in shear. The minimum shear reinforcement ratio of RC beams must be provided around the longitudinal rebars. Thus, the stirrups with different patterns have a significant benefit for improving the RC beam. In this paper, the performance of specimens with different spiral stirrups using ANSYS programs is investigated by comparing them with conventional stirrups of RC beams. One statement on the experimental results has been obtained from previous research Karayannis et al. [17]. The behaviors of these experimental beams are compared with finite element analysis of the identical beams. It is found that the behaviors of the experimental beam in comparison with the behaviors of the numerical beam are slightly different. Based on the FE analysis, the shear strength results demonstrated the mean accuracy and standard deviation of about 0.994 and 0.028, respectively, compared with the experimental test. Furthermore, the curve determined from FE analysis is consistent with the experiment data. The results give knowledge about the importance of spiral stirrups of the beam, and the most effective method among the investigated cases.
