Abstract: The analytical solution of variational analysis for prestressed frame is investigated. Combined with experiment of typical prestressed frame structure, the effective flange width of prestressed concrete beam is studied in details. Results show that the equivalent width of prestressed concrete bean can describe the real stress state. In engineering practice, short-lived state of prestressed concrete stress calculation is required. Prestress can change the two-way concrete floor load transfer law. The results of this work can provide reference for the design and calculation of prestressed concrete slab system.

Key words: prestressed concrete, beam-plates system, effective flange, architectural design, finite element method
