The 35 meter-span prestressed concrete frames are used for Jiefang Street gymnasium in Changchun. The following problems in designing these frames are analyzed: how to determine the material of the frame, prestressing techniques, profile of prestressing strand; how to calculate external loads and internal loads, the effect of prestressing; how to compute areas of prestressing strands and non-prestressing steel in prestressed concrete girders and top-story edge columns;  how to stretch and anchor the prestressing strands; how to dispose the prestressing strands in the frame. The general principles and method for prestressed concrete frame are given. All these are the theoretical basis for design of this gymnasium. Also, these may be reference to design homogeneous building structures.
