Abstract:General solutions are presented for selecting economically optimum cross sections for prestressed concrete flexural members. Such a solution for simply-supported girders of rectangular cross section, for any span and load, assuming the wire prestressed after setting of the concrete and full dead weight to act during the prestressing operation, leads to a design procedure which, in the case considered is extremely simple and rapid to apply. It also permits comparisions and studies related to the critical cross section to be made in a more general and conclusive manner. For cross sections other than rectangular, the number of variables making the solution more indeterminate in nature, a similar direct solution is not obtainable. However, a rapid way of obtaining the minimum areas of concrete and steel required is suggested.
