RATIONAL DESIGN TO CONTROL THE OPENING OF CRACKS IN UNBOUND POST-TENSIONED SLABS

A METHOD OF USING THE EFFECTIVE STRESS IN THE TENDON TO CONTROL THE FORMATION OF WIDE CRACKS IN UNBONDED PRESTRESSED CONCRETE CONSTRUCTION IS DESCRIBED. A NUMERICAL EXAMPLE IS INCLUDED TO SHOW THE APPLICATION OF THE DESIGN METHOD. THIS METHOD WAS INCORPORATED INTO A COMPUTER PROGRAM FOR THE DESIGN OF CONTINUOUS SPANS OF PRESTRESSED POST-TENSIONED CONCRETE. AN OPTION IN THE PROGRAM PERMITS THE USER TO DETERMINE THE DEGREE OF PROTECTION HE DESIRES BY SPECIFYING A SERVICE OVERLOAD FACTOR IN THE INPUT DATA.
