 |
YIELD CURVATURE HAS BEEN FOUND TO BE DIRECTLY PROPORTIONAL TO εy/D |
|
FIG. 2 YIELD CURVATURE ASSESSMENT |
|
|
|
 |
FOR SECTIONS OF SAME DIAMETER AND
WITH SAME MATERIALS PROPERTIES, Фy
IS A CONSTANT AND My IS PROPORTIONAL TO THE STIFFNESS |
|
FIG. 3 RELATION BETWEEN STRENGTH AND STIFFNESS |
|
|
|
 |
KEEPING CONSTANT THE AXIAL LOAD
RATIO, Icr/Ig IS PROPORTIONAL TO
THE LONGITUDINAL STEEL RATIO |
|
FIG. 4 CRACKED TO GROSS INERTIA RATIO VS. LONGITUDINAL STEEL RATIO |

THESE FIGURES SHOW THE RELATION
BETWEEN STRAIN AND THE PRODUCT
OF CURVATURE AND DIAMETER. THE
RELATION IS ALMOST LINEAR. |
