Precast Prestressed Concrete Folded Plate Industrial Building System

Both roof and bearing walls for an industrial building in Honduras were made of precast, prestressed concrete folded plates, some with window and skylight openings. Using design and construction methods developed in China, the precast flat plates and V-sections were assembled with joints formed and cast in place to unify the stucture. This paper presents the design concept showing how W-shape sections were made by combining the flat and V-shape panels. Details of panel production and erection and joint construction are presented.
