Abstract

The integrity of Post-Tensioned (PT) concrete slabs is highly dependent on the design of the
anchorages zone and the anchorage system used. Using new anchorage devices may require much experimental
testing, particularly when we need to examine several parameters. This research aims to numerically investigate
the stresses at anchorage zones when using a new anchor device. To that aim, a 3D finite element model for
the slab and the anchor device was established using a finite element program. The numerical modelling
technique and parameters were verified using the results of experimental work from literature. Anchorage
device transversal ribs, ties around the device, and reinforcement in the end block slab were examined to study
their effect on the end block stresses. It was found that the studied parameters have a considerable impact on
the behaviour of the end block. Also, numerical modelling was successful in studying anchorage zones stresses
when using new anchorage devices.
