An Introduction to Prestressing with Post-Tensioning of Highway Box Girders

Introductory technical guidance for civil and structural engineers and construction managers interested in design and construction of box girder highway structures. Here is what is discussed: 1. INTRODUCTION 2. CROSS SECTION PROPERTIES AND SIGN CONVENTION 3. STRESS SUMMARIES IN A PRESTRESSED BEAM 4. SELECTION OF PRESTRESSING FORCE FOR A GIVEN ECCENTRICITY 5. PERMISSIBLE ECCENTRICITIES FOR A GIVENPRESTRESSING FORCE 6. EQUIVALENT FORCES DUE TO POST-TENSIONING AND LOAD BALANCING 7. POST-TENSIONING IN CONTINUOUS GIRDERS 8. TENDON PROFILES-PARABOLIC SEGMENTS.
