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.
