Behaviour of reinforced and prestressed concrete folded plate structures

Behaviour of simply supported reinforced concrete and prestressed concrete folded plate roof structures is studied using finite element method. The choice of prestressing on the plate or on the edge beam for efficient structural behaviour has been analysed. Effect of different types of intermediate transverse stiffeners such as solid diaphragms, ribs, and ties are evaluated and compared. Study is extended to multiple folded plate roofs to cover a large column free space.
