- Synopsis:
- On RC columns, it was assumed that the shear failure is caused when Mohr's stress circle drawn by using the axial stress of concrete and the confining stress of hoops touches Coulomb's criterion. And, the predicting method of the shear strength and the deformation capacity on RC columns based on Mohr-Coulomb's criterion, that was a reasonable method of considering the state of the stress in concrete, was proposed, then it compared with the experimental results in the past. AS a result, the shear strength and the deformation capacity could be predicted more accurately than the methods of the past.
