LIMIT DESIGN OF PRESTRESSED CONCRETE BRIDGES

THIS ARTICLE PRESENTS A LIMIT DESIGN THEORY FOR THE DESIGN OF PRISMATIC AND NONPRISMATIC CONTINUOUS PRESTRESSED CONCRETE GIRDER BRIDGES SUBJECTED TO MOVING LOADS. AN EXAMPLE HAS BEEN WORKED OUT TO ILLUSTRATE THE APPLICATIONS OF THE THEORY. IN COMPARISON WITH OTHER METHODS THE PROPOSED SYSTEM REALIZES CONSIDERABLE SAVINGS. THE DESIGN ENGINEER COULD CARRY OUT THE LIMIT ANALYSIS SO THAT IT GIVES A MORE ACCURATE REFLECTION OF ACTUAL CONDITIONS IN THE STRUCTURE AND, THEREFORE, A REALISTIC FACTOR OF SAFETY. WHILE NOT FULLY ADOPTED, THE CONCEPT OF LIMIT DESIGN FOR REINFORCED CONCRETE HAS ALREADY BEEN INCORPORATED IN VARIOUS FORMS IN THE ACI BUILDING CODE AND IN THE CODES OF PRACTICE OF THE U.K., U.S.S.R., DENMARK, AND NORWAY. /DOT/
