Nowadays, the popular building structural materials are becoming rich and colorful with large price difference.
Not only new high-tech materials are more expensive than the common materials, but price difference also happens to the same type of materials.
Generally, price difference of structure materials is not the concern of architects, but its economy is indeed the concern of structure designer.
The economy of all kinds of structure materials mainly reflects from the materials dosage.
Sometimes architects’ lack of scientific analysis and the optimization of their design results may attribute to the overuse of structural materials.

Science and technology oriented SMES have become the new force that develops self-innovations in Shenzhen.
Especially in the fields of biomedicine, internet, new energy and new materials ect, there are a large number of private enterprises and SMES developing speedily such as Haiwang, A8, Topraysolar, Green Eco-manufacture,  Woer Heat-Shrinkable Material Co.
These 61 enterprises are all from high-tech fields of new economic modes such as electronic information, new materials, biochemistry, modern transportation and high-end service industries ect.

Composite materials are mostly used in applications where stiffness-to-weight or strength-to-weight ratios are critical.
Introduction Nowadays trends in construction is to use lightweight and longlife materials, which makes FRP and sandwich composite materials to have a larger aplicability especially due to their strength and stiffness [1,2,3,4].
The shell is reinforced with longitudinal web stiffeners having various geometries and made out of various materials (composites, aluminum and steel).
