THE NATURE OF PRESTRESSED STEEL STRUCTURES

THE PRINCIPLES GOVERNING THE DESIGN, APPLICATION CONSTRUCTION AND BEHAVIOR OF PRESTRESSED STEEL BEAMS ARE DISCUSSED. ONLY ONE TYPE OF PRESTRESSING IS CONSIDERED AND THAT IS PRESTRESSING USING CABLES, STRANDS OR RODS. SEVERAL TYPES OF BEAM STRUCTURES ARE CONSIDERED INCLUDING PRESTRESSED I-SHAPED BEAMS, PRESTRESSED COMPOSITE BEAMS AND PRESTRESSED CONTINUOUS BEAMS. IN EACH CASE THE BEHAVIOR OF THE STRUCTURE IS PRESENTED ALONG WITH COMMENTS ON THE POSSIBLE ECONOMY TO BE ACHIEVED. A COMPARISON IS GIVEN BETWEEN CONVENTIONAL AND PRESTRESSED COMPOSITE BEAMS AND THE RESULTS SHOW PROMISE FOR PRESTRESSING. THE EFFECTS OF PRESTRESSING ON SIGNIFICANTLY REDUCING BENDING MOMENTS IN CONTINUOUS BEAM CONSTRUCTION ARE DISCUSSED. SEVERAL EXAMPLES OF PRESTRESSED STRUCTURES ARE PRESENTED. /AUTHOR/
