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.
