In this paper , MIDAS GENw for commercial structural analysis program and Visual Basic 6.0 was applied to evaluate the crack width and crack shape of reinforced concrete beams without actual experiments.
The results of this study were as follows :
1. The cracks in flexural stress in modeling three elements(M4,M6 and M12) showed similar tendency. Meanwhile, M12 modeling results for the diagonal tension crack by shear showed good agreement with experimental results.
Also, diagonal tension crack have occurred at the position of d, far from the support point. Consequently, it was confirmed that design standard for the calculation of control reinforcement against diagonal tension crack should be applied for the position d.
2. In the analysis of failure behavior of beam, maximum crack widths with respect to each failure mode(e.g., flexural failure, diagonal tension failure) have been compared. It was found that failure behavior of beam was mainly affected by the flexural crack, rather than diagonal tension crack.
