Abstract	IN ORDER TO CALCULATE THE MOMENT CARRYING CAPACITY OF AN UNBONDED, SIMPLY SUPPORTED, PRESTRESSED CONCRETE BEAM, IT IS NECESSARY TO DETERMINE THE STATE OF STRESS THROUGHOUT THIS INTERNALLY INDETERMINATE SYSTEM. THE PROBLEM IS COMPLICATED BY NON-LINEAR MATERIAL BEHAVIOR AND VARIATION IN THE CROSS SECTION WITH MOMENT DUE TO CRACKING OF THE TENSION ZONE. A SOLUTION TO THIS PROBLEM IS PRESENTED FOR THE CASE OF A BEAM WITH RECTANGULAR CROSS SECTION SUBJECTED TO A UNIFORMLY DISTRIBUTED LOAD. THE APPLICABILITY OF THE SOLUTION IS DEMONSTRATED BY COMPARISON WITH TEST RESULTS. /TRRL/
