Abstract: In this paper,we have contrast destructive tests on two pieces of prestressed overlapping continuous beams against a piece of cast in situ continuous beam and two pieces of prestressed overlapping frame against cast in situ frame,by which the ductility performance of prestressed overlapping flexural unit has been researched,providing test reference for the general application of prestressed overlapping flexural unit.
