DESIGN OF PARTIALLY PRESTRESSED CONCRETE BEAMS

THE DESIGN IS DISCUSSED OF PARTIALLY PRESTRESSED CONCRETE BEAMS, COVERING ALSO THE TWO LIMITING CASES, I.E., FULLY PRESTRESSED AND ORDINARY REINFORCED CONCRETE BEAMS. THE CROSS SECTION IS BASED ON ULTIMATE LOAD CONDITIONS AND THE REQUIRED EFFECTIVE PRESTRESSING FORCE IS RELATED TO AN ALLOWABLE NOMINAL CONCRETE TENSILE STRESS WHICH FOR A DEFINITE REINFORCING PERCENTAGE RATIO INSURES THAT UNDER SERVICE LOAD THE WIDEST CRACK DOES NOT EXCEED A PERMISSIBLE WIDTH. THE TYPE OF STEEL REQUIRED FOR THE NONTENSIONED REINFORCEMENT IS GOVERNED BY THE PERMISSIBLE MAXIMUM DEFLECTION. SIMPLE, WELL-KNOWN FORMULAS ARE USED. /AUTHOR/
