TEST OF UPPER ANCHORAGE OF NO. 14S COLUMN BARS IN PYLON DESIGN

A TEST RUN ON A FULL SIZE MODEL REPRESENTING A ONE-FOOT SLICE THROUGH THE UPPER PART OF A PYLON SHOWED THAT NO. 14S COLUMN BARS OF A432 GRADE STEEL COULD BE ADEQUATELY ANCHORED IN 4200 PSI CONCRETE FOR THEIR FULL YIELD STRENGTH IN TENSION PRODUCED BY UNBALANCED LIVE LOAD, EVEN WITHOUT EXTENDING THEM THROUGH THE TOP BEAM TENSILE REINFORCING STEEL. THE FAILURE WAS IN FLEXURE (PLUS DIRECT STRESS) IN A MANNER GIVING BOTH WARNING AND TOUGHNESS. /AUTHOR/
