structural behaviour and span of folded plates
since the form of folded plate is different to the form of its moment diagram, each slice in it works with bending stress, as seen in figure . this mean that each slice is similar to a beam. folded plate car be used for span between 10m and 150m. since they have more moment than thin shells, they should be thicker. the teacher training college in leeds, uk , has a simple triangular prismatic folded plate roof. the span of the folded plate is around 20m the width of each folded plate is 35m and depth of the plate is 10.20cm . this means that the span to thickness ratio in this building is around 196.
