PERFORMANCE OF CONCRETE BRIDGES REINFORCED WITH HIGH- STRENGTH STEEL: FIRST INTERIM REPORT

TWO EXPERIMENTAL BRIDGES REINFORCED WITH HIGH-STRENGTH STEEL WERE INSTRUMENTED TO DETERMINE THEIR LIVE-LOAD AND LONG-TERM DEAD-LOAD PERFORMANCE. THE RESULTS OF A 4-1/2 YEAR STUDY OF DEFLECTIONS AND CRACK FORMATION ARE PRESENTED AND COMPARED TO THEORETICAL VALUES. IT IS CONCLUDED THAT PRESENT DESIGN TECHNIQUES ARE ADEQUATE FOR SIMPLE-SPAN STRUCTURES, BUT THAT MORE SOPHISTICATED TECHNIQUES ARE REQUIRED FOR SATISFACTORY PREDICTION OF THE LONG-TERM BEHAVIOR OF CONTINUOUS SPANS. /AUTHOR/
