Nature also uses the principle of folding to create light weight structures. Many plant leaves are unfolded while growing and thus stabilize large surfaces with a minimum of matter. Simplicity, homogeneity, flexibility and variety of forms, economy, and generation of complex geometries based on simple principles are the main characteristics of origami FOLDED PLATES ,40

A folded plate is an example of a 3-dimensional or space structure ,40

 If the same piece of paper is folded then it will be capable of supporting one hundred times its own weight ,40

This problem can be rectified by using transverse stiffeners at the ends. The folded plate acts as a beam and can support even greater loads ,40

The result of this bending can be seen in the animation opposite ,40

Main structure of the port terminal is a folded plate structure that allows for minimal columns to create free flowing space while having the freedom to create a undulating landscaped roof for the pleasure and enjoyment by the public ,40

The earliest folded plate solutions […] drew from their close resemblance to corrugated plate and cylindrical shells. The underlying idea is quite simple: longer spans can be accommodated with relatively small increases in weight by enlarging the lever arm of the structure; the top and bottom chords of each slanted slab house the main reinforcements while the shear stresses are absorbed across the sloping sides ,40
