LIMIT STATE DESIGN OF HIGHWAY BRIDGES-A STUDY OF THE IMPLICATIONS WITH PARTICULAR REFERENCE TO CERTAIN EXAMPLES

ANALYTICAL AND EXPERIMENTAL STUDIES WERE CARRIED OUT INTO VARIOUS ASPECTS OF LIMIT STATE DESIGN WHEN APPLIED TO HIGHWAY BRIDGES. TO OBTAIN AN INDICATION OF THE INHERENT LOAD FACTORS AGAINST THE VARIOUS APPROPRIATE LIMIT STATES, THREE TYPICAL BRIDGES WERE THEORETICALLY INVESTIGATED. THE PREDICTED LOAD FACTORS WERE COMPARED WITH THOSE PROPOSED FOR USE WITH NEW DESIGN PROCEDURES. THE BRIDGES TREATED WERE OF PRESTRESSED T-BEAM AND SLAB, COMPOSITE STEEL AND SLAB, AND STEEL BOX GIRDER CONSTRUCTION. THEORETICAL MARGINS OF SAFETY AGAINST COLLAPSE WERE DETERMINED BOTH FOR VEHICLE AND BRITISH STANDARD FORMULA LOADING. COMPARISON SUGGESTS THE B.S. LOADING MIGHT BE SATISFACTORILY ADOPTED AS 'CHARACTERISTIC'. THE INVESTIGATION SHOWS THAT, SHOULD THE RECOMMENDED LOAD FACTORS BE ADOPTED IN FUTURE DESIGN DIRECTIVES, A SIGNIFICANT ECONOMY IN THE COST OF CONSTRUCTION MAY BE EXPECTED FOR MOST CLASSES OF HIGHWAY BRIDGE. /AUTHOR/
