Extended information:

The diameter of the bending center of the steel bar is 2.5d, and the straight part is 3d. The theoretical calculation value of the increased length of the steel bar hook is: 6.25d for the counter-rotated semicircular hook, 3.5d for the straight hook, and 4.9d for the inclined hook. ?Bend the steel bar. The bending diameter D at the bend in the middle part shall not be less than 5 times the diameter of the steel bar. ?

Stirrups. The ends of the stirrups should be hooked, and the form of the hooks should meet the design requirements. Stirrup adjustment is the difference or sum of the added length of the hook and the bending adjustment value, which is determined by the outer or inner wrapping size of the stirrup amount. The cutting length of the steel bars should be comprehensively considered based on the component size, thickness of the concrete protective layer, steel bar bending adjustment value and additional length of the hook.

The blanking length of straight steel bars = the length of the component - the thickness of the protective layer + the additional length of the hook. The cutting length of the bent steel bar = the length of the straight section + the oblique bending length - the bending adjustment value + the added length of the hook. Stirrup blanking length = stirrup inner circumference + stirrup adjustment value + hook added length?
