Shear reinforcement plays an important role in the shear resisting capacity of the beam. It is necessary to study the effects of shear cracking behavior in the Reinforced Cement Concrete (RCC) beams. Various efforts have been put forth to study the effects of cracking and crack control in RCC elements. An analytical study was done on three RCC beams (A1, A2 and B1) using ANSYS 15.0 software and various parameters, such as shear span to depth ratio, stirrup configuration, crack patterns and load required for first crack initiation, were studied. Beams with unsymmetrical shear spans were prepared to study the effect of shear span to depth ratio; the depths of beams varied from 200 mm to 350 mm (ANSYS software). The effect of shear configuration is also studied where the beam is designed in such a way that right and left shear spans were spaced at 100 mm and 200 mm, respectively. Load required for first crack is calculated numerically and compared with the results obtained in ANSYS software. The crack patterns obtained in ANSYS software were compared with earlier works. Stress intensity factor for beams was obtained from ANSYS software.

 
 

Beams are most commonly used structural members in structural mechanism used in civil, aeronautical and naval engineering. In structural analysis and engineering, the most important aspect is damage. Damage analysis is performed to ensure the safety of structures. During operations, all structures are subjected to many degenerative effects which may cause initiation of structural defects such as cracks. As time progresses, structure leads to global failure or sudden failure. To prevent unexpected or sudden failure, the detection of cracks in the earlier stage is essential. Various techniques have been developed for early detection of crack depth, location, size and pattern of damage in structures. Many nondestructive techniques have been developed for crack location worldwide. The fast and economical method for crack or damage identification is vibration-based method.
