Unified 1-effective procedures for partially cracked non-prestressed and prestressed member curvatures and deflections are summarized, Deflections computed by numerical integration of curvatures (using !e in the fourth power equation), and also by direct calculation (using l'e in the third power equation) are illustrated for a typical single-T beam designed as a partially prestressed member in accordance with the ACI Code. The numerical integration procedure readily lends itself to computer solution for both determinate and indeterminate structures. Results by the two methods are seen to be in close agreement.
