Both roof and bearing walls for an industrial building in Honduras were made of precast, prestressed concrete folded plates, some with window or 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 structure. This paper presents the design concepts, showing how W-shape sections ere made by combining the flat and V-shape panels. Details of panel production and erection, and joint construction are presented.
