INVESTIGATION OF A FULL-SIZE CONTINOUS CONCRETE HIGHWAY BRIDGE PART I

A FULL-SIZE THREE-SPAN CONTINUOUS CONCRETE HIGHWAY BRIDGE WAS BUILT OFF-THE-HIGHWAY TO PERMIT A LONG-TERM STUDY OF THE TIME-DEPENDENT BEHAVIOR OF SUCH A STRUCTURE SUBJECTED ONLY TO DEAD-LOAD AND ENVIRONMENTAL EFFECTS. THE BRIDGE WAS OF A TYPE WHICH HAS EXHIBITED EXCESSIVE DEFLECTIONS AND ABNORMAL CRACKING EVEN THOUGH DESIGNED IN COMPLETE ACCORDANCE WITH AASHO STANDARD SPECIFICATIONS. MEASUREMENTS WERE MADE OF REACTIONS, DEFLECTIONS, CONCRETE AND STEEL STRAINS, LONGITUDINAL MOVEMENTS AND TEMPERATURES OVER A PERIOD OF ONE YEAR IN AN ATTEMPT TO DETERMINE THE INTERRELATIONSHIP OF SUCH FACTORS AND POSSIBLE CAUSES FOR THE DETRIMENTAL BEHAVIOR. THE CONDITION OF EXCESSIVE CRACKING OR SAG DID NOT OCCUR IN THIS BRIDGE, UNFORTUNATELY. RELATIVE CORRELATIONS OF BAR STRESSES, SPAN DEFLECTIONS AND REACTIONS WITH TEMPERATURE WERE OBTAINED, ALTHOUGH DIRECT NUMERICAL RELATIONSHIPS WERE NOT POSSIBLE. /BPR/
