In prelminary design to determine concrete member size or cost comparisions, time-saving methods involving a reasonable degree of accuracy are desireable. Moment coefficant for both positive and negative moments are limited to spans which are approximately equal. In the proposed method coefficients are used for negative moments only. With known negative moments, positive moments are easily determined by the application of simple statics. Whether the method has the requisite accuracy for a final design depends largely upon the implicitness of the designer's faith in elastic stress analysis.
