FOLDED PLATE IS A ROOF WHICH HAS BEEN MOULDED TO A SHAPE. WHICH IS IN RCC, STEEL ETC.ITS FOR LARGE COVERING

FOR OPEN SPACES

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

WHEN A THIN SHEET OF PAPER RESTS BETWEEN TWO SUPPORTS IT WILL BEND DUE

TO THE FACT THAT IT HAS INSUFFICIENT STRENGTH TO CARRY ITS OWN WEIGHT

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

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

IF THE LOAD IS INCREASED PAST THIS POINT THEN THE STRUCTURE WILL FAIL

AND THE FOLDS WILL FLATTEN OUT

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

FOLDED PLATES CONSIST OF STRAIGHT PIECES JOINED WITH SHARP EDGES. IT CANNOT BE

MADE AS THIN AS A SHELL DUE TO THE FACT THAT IT IS SUBJECTED TO BENDING.

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

FOLDED PLATES CAN BE SEEN AS A SPACE VERSION OF A RIGID FRAME. FOLDED PLATES ARE BEST FORMED FROM REINFORCED CONCRETE DUE

TO THE FACT THAT THEY CAN BE EASILY CAST. FOLDED PLATES CAN

TAKE THE FORM OF FRAMES AS SEEN ABOVE OR DOMES

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.

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.
