The results show that permissible minimum rolling thickness of asymmetrical rolling only exists within a specific range of cross-shear ratio, which is termed the cross-shear zone proportion of the whole deformation zone.
Stirrups, as anchor shear reinforcement, are proportioned using the anchor steel capacity in shear as specified by ACI 318-14, and the nominal yield strength of reinforcing steel.
"As those industries have shorn jobs, the proportion of families with middle incomes has declined," says Douglas Hall, director of the Economic Analysis and Research Institute at the Economic Policy Institute, an economics-based think tank in Washington, D.C. "Manufacturing's role in the economy has changed, and we haven't wrapped our heads around what the implications are".
The proportion of shear deformation decreases with the increase of shear span-to-depth ratio, and on the contrary, the proportion of flexural deformation increases.
By analyzing the proportion of shear and flexural deformation, it can be concluded that the shear contribution to the total deformation for the diagonally cracked RECC column is significant, especially for the RECC columns with low shear span-to-depth ratios. .

With the development of inclined cracks, the proportion of shear deformation increases, and gradually becomes stable.
This allows a spectrum of time-dependent behaviour depending on the proportion of shear to extensional fractures, fluid viscosity, rate of overpressure generation, etc.
Therefore, the three-point bending span is varied to modify the stress field and specifically the proportion of shear to normal stress.
The methods for proportioning anchor shear reinforcement are summarized in Petersen and Zhao (2013).
