TEMPERATURE AND SHRINKAGE STRESSES IN A CONCRETE BRIDGE PIER

A CONCRETE BRIDGE PIER WAS INSTRUMENTED TO VERIFY AASHO 1964 REQUIREMENTS FOR COEFFICIENT OF THERMAL EXPANSION, TEMPERATURE VARIATION, AND SHRINKAGE. DATA ON THE MAGNITUDE AND DISTRIBUTION OF STRESS IN THE FOOTING, AN OUTSIDE COLUMN, AND THE CAP BEAM WERE COLLECTED FOR ALMOST 300 DAYS. THE MOMENT MEASURED AT THE PIER'S TOP CORNER DUE TO SHRINKAGE, TEMPERATURE, AND DEAD LOAD WAS 150 KIP-FT LOWER THAN THE DESIGN MOMENT OF 450 KIP-FT. THE EFFECTIVE TEMPERATURE DIFFERENTIAL CREATING BENDING IN THIS FRAME WAS 20 DEG F PLUS OR MINUS 5 DEGREES. THE REQUIRED 0.0002 SHRINKAGE COEFFICIENT APPEARED REASONABLE. /AUTHOR/
