The structural plan arrangement is optimized. Some factors such as floor members, self-weight of structure, construction process of prestressing having influence upon cracking capacity are discussed. Mechanics of periphery members are changed according with prestressing in sophisticated structure. The design method is put forward to satisfy the technical specification.Keywords:prestressed；frame；transfer beam
