Title: Recommendations for the Degree of Prestressing in Prestressed Concrete Structures
Author(s): Fritz Leonhardt
Publication: Special Publication
Appears on pages(s): 269-286
Keywords: crack width and spacing; deformation; partial prestressing; performance; prestressed concrete; safety factor; serviceability; structural design; tensile stress
Abstract:Experience and some damages in the last 30 years teach that full prestressing is often not the best solution for prestressed concrete structures. Better service performance can be obtained with partial prestressing. Serviceability criteria are proposed to meet performance requirements. Cracks with limited crack width are harmless, but crack width control must be improved and this can be done by partial prestressing. Rules are given for a reasonable choice of the degree of prestressing.
