Abstract:
Modern construction techniques make use of anchors and fixings that cause highly concentrated loading on concrete. An experimental program has been carried out to study the failure mechanism and ascertain the load-penetration behavior of 13 to 32 mm diameter steel punches. It is shown how the bearing strength varies as a function of the loaded area, concrete grade, and maximum aggregate size. Failure stresses are given and design values are proposed.
