(PDF) Experimental study of splitting and flexural cracks ...

In par-ticular, flexural cracks are strictly related to the maximum re-bar slip which depends on the local micro-crushing of the porous concrete layer in front of the rib [9][10][11]. Splitting cracks are caused by rib-wedging action and govern the bond strength and stiffness [12,13] (Figs lb, c).There is a growing interest for bond after ...
