LOCATING THE CRITICAL FLEXURAL STRESS POINTS IN SINGLE AND DOUBLE DRAPED PRESTRESSED MEMBERS

For prestressed concrete members with draped tendons, a significant error may result when the service flexural stresses are computed only at 0.4L or 0.5L. A computer oriented method is presented which precisely locates the points of critical service stresses for a uniformly loaded, simple span member with one or two drape points. When double drapes are specified, the procedure calculates the optimum distance between draping points. Equations are presented which express the allowable serive loads as limited by the critical points. Flow charts are provided to facilitate modification of existing computer programs to include this technique. /Author/
