Very light form of construction.
Folded plate roof construction details.
Folding plate is a light but stiff form of roofing capable of carrying all normal roof ioads.
Folded plate structures are assemblies of flat plates or slabs inclined in different directions and joined along their longitudinal edges.
Rectangular trapezoidal or trian gular.
Forming a folded construction can be of various shapes.
Folded plate surfaces folded plate frames.
Folded plate roofs are also easy to assemble which further reduces the related costs and shortens installation time as well.
A plywood folded plate is a structural component consisting of a number of diaphragms made of plywood skin and sawn timber frame connected to form a series of vee beams.
To span 30 m shell thickness required is 60 mm only.
Step 1 figure 4 1a consider an imaginary one foot strip cut along the center line of the proposed folded plate.
Introduction to folded plate structure system.
By combining these elements we get different forms resulting in a variety of shapes and remarkable architectural expression.
The slab between columns must be designed as a beam and it may be convenient to extend the main roof slab as a cantilever canopy.
Terminology and construction details are illustrated in figure 1.

They will make you physics.
Lectures by walter lewin.
This study vas made with 8 aluminum models of varying plate thickness span length and roof slope.
Folded plate construction is less material intensive than other types of roofing systems used for industrial or commercial applications which also means that folded plate roofs are cheaper.
In this way the structural system is capable of carrying loads without the need for additional supporting beams along mutual edges.
As you read them also examine the details on figure 4 1 a through e.
The usual upturned edge plate can be eliminated and the roof structure can be made to appear very thin if the edge plate is replaced by a series of columns.
Based on geometric shape folded structures can be divided into fig.
