AN INVESTIGATION OF DESIGN CRITERIA FOR STRESSES INDUCED BY SEMI-INTEGRAL END BENTS: PHASE 1 FEASIBILITY STUDY

THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE FEASIBILITY OF DEVELOPING A RATIONAL DESIGN CRITERIA FOR BRIDGES WITH SEMI-INTEGRAL END BENTS. THE STUDY CONSISTED OF FIVE MAJOR PARTS: (1) A LITERATURE SEARCH AND EVALUATION OF FACTORS INFLUENCING BRIDGE BEHAVIOR, WHICH INDICATED THE MAJOR PARAMETERS TO BE CONSIDERED ARE THERMAL EFFECTS, HUMIDITY, AND CREEP AND SHRINKAGE: (2) A SURVEY BY QUESTIONNAIRE OF CURRENT DESIGN PRACTICE, WHICH ESTABLISHED THAT THERE IS NO SIMPLE, RATIONAL DESIGN CRITERIA CURRENTLY AVAILABLE THAT THERE IS A WIDE VARIANCE IN METHODS, IF ANY, USED FOR CONSIDERATION OF SUCH STRESSES, AND THAT BRIDGE DESIGN ENGINEERS WOULD WELCOME A SIMPLE, RATIONAL CRITERIA; (3) FIELD INSPECTION OF THE BEHAVIOR PATTERNS OF SELECTED BRIDGES; (4) THEORETICAL ANALYSIS OF POTENTIAL MAGNITUDES OF STRESSES AND MOVEMENTS INDUCED BY TEMPERATURE DIFFERENTIALS; THESE STRESSES APPROACHED 20 PERCENT OF THE DEAD AND LIVE LOAD STRESSES FOR THE RESTRAINED STRUCTURE, WHICH WHEN COMBINED WITH OTHER FACTORS COULD CAUSE A SIGNIFICANT INCREASE IN STRESSES AT SPECIFIC LOCATIONS; AND (5) RECOMMENDATIONS FOR INSTRUMENTATION OF A PROTOTYPE BRIDGE. THE STUDY INDICATES THAT IF THE THEORETICAL APPROACH CAN BE SUBSTANTIATED BY EXPERIMENTATION, THE DEVELOPMENT OF A SIMPLE AND USABLE RATIONAL DESIGN CRITERIA WOULD BE BOTH FEASIBLE AND DESIRABLE. /FHWA/
