An experimental investigation of sheet pile interlock behavior under lateral pressure
… Three tests from each lot of 6 incorporated pretensioning of the assembly prior to application of the lateral pressure; whereas, the remaining tests initiated lateral loading of the assemblies while they were in a slacked state. The results from the tests were generally grouped according to …

Spannbetonfertigteile mit teilweiser Vorspannung aus hochfestem Beton
… by the increase in bond strength of the pretensioning tendons. In this paper the investigation results of the bond properties of prestressing steel in the transmission zone of prestress, in the area of cracks and in the anchorage zone are presented. In order to investigate the behaviour …

An Investigation of Anchor Nut Loosening and Review of Tightening Procedures for Anchor Rods in Highway Ancillary Structures
… first snug-tightened using a wrench before fully pretensioning them as per the current specifications. The snug-tight condition is vaguely defined at present and needs revisions to avoid any under-tightening or over-tightening. Galvanization and overtapping of the anchor nuts also pose a potential …

Influence of side walls and undulated topography on viscous gravity-driven film flow
… of the flow. Capillary elevation leads to a pretensioning of the free surface, which tends to stabilize the free surface, just as the additional no-slip condition at the wall does. The emerging of a velocity overshoot in the capillary elevation on the other hand leads to a destabilization of …

Zum Verbund- und Querkrafttragverhalten von Spannbetonträgern aus ultra-hochfestem Beton
Within the priority program SPP 1182 of the German Research Foundation (DFG), the bond behavior of strands in ultra-high performance concrete (UHPC) as well as the shear bearing behavior of pretensioned girders were investigated at the Institute of Structural Concrete at the RWTH Aachen University. …
