The origin of arched corrugated metal truss roof

In the forties of the last century, some American structure designers inspired from the structure and the shape of the natural plant skin texture began to seek a sheer material through the corrugated stiffening which methods of large span structures.They build a mechanical model of thin steel plate, and analyze the reasonable structure in theory.On the way to achieve this structure, the structure division and the mechanic come together.Structural requirements of the mechanical engineer to develop the production of a corrugated thin wall structure of the unit,which is a metal truss roof molding machine.In 1955, the United States used this metal truss roof for military (fighter base, barracks, etc.).Low cost, amazing construction speed, good construction effect, metal truss roof attracts more and more researchers and users.This kind of structure develops quickly, especially the introduction of computer numerical control make the structure of the metal truss roof simple and fast.However, due to various reasons (such as the economy, etc.), the scientific research and the development of the sturcture production unit is limited to a number of major companies (such as the United States MIC) of United States, Britain and other countries.Therefore, the international market of this structure is a monopoly of these companies, which is very bad for the development of metal truss roof and further promote the development.

In the last century 80's, china had sent commissioners to the United States to investigate, but the introduction of foreign technology is very difficult: first, the cost of equipment is very expensive; Secondly, foreign technology is not in line with China's comprehensive technical standards (such as material, load, etc.); and the United States retained in the structural analysis of the key technologies.
