Crack spacing
Webto keep crack widths small. This has long been an accepted practice. As shown by Vetter,6 for example, crack widths are kept small by making the distance between cracks small. Because crack spacing is inversely related to the bond between the concrete and steel, crack control generally improves as the ratio of bar perimeter to bar area increases.
