Magnetic detection of prestressing steel fractures in prestressed concrete
Materials and Corrosion, 1998The paper deals with the remanent magnetism method (RM-method) to identify unsafe prestressed structures concerning sudden collapses of structural components due to fractures of the prestressing steel. It describes the non-destructive testing method that allows to localize fractures of single prestressing steel wires even in post-tensioned tendons. The

Prestressed Concrete Girder with Multistage Prestressing Concept
ACI Structural Journal, 2003Short- and medium-span bridges commonly use prestressed concrete (PSC) I-type girders in their construction. Prestressing in traditional PSC girders is usually applied once at the beginning stage of fabrication. The magnitude of the prestressing force is limited within allowable stresses at various construction stages. Consequently, for longer spans, a

Prestressed anchored cables have been widely used in slope reinforcement engineering, but prestress variations in these cables are not fully understood, particularly for anchored cables bolted into strata that have undergone time-dependent excavation ...

Prestressed pin-jointed structures—Flexibility analysis and prestress design
Computers & Structures, 1988Two classes of prestressable structures exist. Class I are geometrically rigid and statically indeterminate structures. Class II are statically and kinematically indeterminate structures with infinitesimal mechanism. In structures of class I, prestress by means of imposed lack of fit can substantially enhance the design, particularly when failure is ...
