Abstract:
Presents an optimum design for a given prestressed concrete member, chosen from an existing shape library and a given external load system. It is emphasized that, as part of the given data, the tendon diagram is determinant in designing a prestressed concrete member. The analysis is based on the elastic behavior of the member, and a realistic investigation of the capacity of the member is performed. The whole process implies an appreciable volume of computations and is suitable for digital computers. A design aid for the initial and final stages of the prestressed concrete member is also presented.
