Chapter5Me asurem ents ofDamageand Size Effect

The concrete cone capacity of headed anchor bolts subjected to axial tension load was

experimentally investigated using 35 concrete specimens of three different sizes. The

dimensions of the test specimens were varied in proportion to the embedment depth h

(h = 50, 150 and 450 mm). Material properties were measured on accompanying speci­

mens. The measured failure loads are compared with other experimental and numerical

investigations. According to the present results the failure loads increase in proportion to

h16, that means close to the prediction by linear fracture mechanics.
