Cellular Solid

Cellular Solid is a network of struts or faces that form the faces of the cells. The simple examples of the cellular solids comes from nature ,such as the bee's honeycomb or a sponge.There are three kinds of cellular solid ; a 2d cellular solid , a closed 3d cellular solid and an open cell 3d cellular solid.
In Architecture these properties of cellular solid have been used in many contemporary design. The 3d voronoi structure that emerge everywhere in Zaha Hadid design or AA DRL students project in London are the examples.The reason is simply the exploitation of the geometry needs a complex and hard-core digital computation.Your 2.0 core 2 duo won't do it for you mate!.The other reason might related to the high cost of the project it self.
The benefit of the cellular solid properties is the infinite variation that comes to only one result : a high strength/weight ratio.Which means that it allows you to have a fairly light structure for a wide span structure. The most intriguing examples are the structure design of Watercube in Beijing. The foam structure of the Watercube allows it to have 70 m column free structure,which makes it the longest space truss span in the world.The structure itself derived from the what so-called Wheaire Phelan structure,known for the most efficient polyhedra configuration to fill up the given volume with smallest surface area (the structure beat Lord Kelvin structure of such the same system).However the development of the system and application in real architecture project are still really limited.This due to its complexity and high cost building.
