| Abstract: | Based on the present China's design specifications in combination with the design theory for reinforced, full-prestressed and part-prestressed concrete structure, a prestressed-degree was suggested as the control index of optimum design for prestressed concrete structure using the complex-shape mathematical optimum method. In the case of a given shape of structure cross-section, the optimum total of prestressed reinforcement and the optimum ratio of the prestressed and non-prestressed reinforcement can be obtained to satisfy the functional restraints and structural restraints. |
