Abstract: Cast-in-place headed studs are world-wide used. In general there are no major concerns with their suitability and performance in concrete. In the meantime undercut anchors have been developed that show similar behaviour. In this paper only the performance under tension and shear is compared. It was not intended to discuss other differences such as costs, installation procedures or convenience in planning of an anchorage.
The comparison shows that the performance characteristics of headed studs and undercut anchors are approximately the same. The main difference is the required member thickness. For the selected undercut system, HDA, it is shown that the required values of the approval document can be drastically reduced. So headed studs and the undercut anchors are comparable and competitive in their performance.
