Abstract

In the present paper results of the finite element study for headed stud anchors loaded in tension (concrete cone failure) are presented and discussed. The numerical analysis was performed using a 3D FE code based on the microplane model. Considered are anchors with extremely large embedment depths (up to 1143 mm). For each embedment depth the size of the head of the anchor was varied in order to account for the influence of pressures under the anchor head. Furthermore, for the anchor group of four anchors, the in- fluence of the head size on the characteristic spacing of anchors was investigated. The results of the finite element study are discussed and compared with the recently performed test results and with current code rec- ommendations.
