This article gives an introduction to the design of single span partially prestressed frame beam with 39.7m length in the training hall of Shandong Sports Technology Institute. The calculation in the design of this engineering is done by the method of degree of prestress,  so the design is clear and easy to calculate. Valuable experience is presented for design of the prestressed super-large span prestressed concrete frame.
Keywords:  large span; prestressed; frame; degree of prestress
