Introduction Composite structure is widely used in engineering structure due to its material designability and excellent structural performance, and a great number of research literatures put forward that composite material is to play an important and indispensable role in the following development of bridge engineering.
This paper studies the decoupling with a kind of rectangular sandwich bar structure that may be used in practical engineering to promote the application of that theoretical method.
And in fact, the composite sandwich thin-walled bar that meets the above decoupling condition exists in actual engineering.
Brief introduction of the author: Zulie Wu, born in Tongliang county, Chongqing city in 1964, is a professor who studied bridge engineering and composite material structure.

About on Low-alloy Coupled Steel Bars Concretes Rigidity and Crack Opening Model Formula Establishment Bing Gao1,a 1School of Civil Engineering, Jilin Architectural and Civil Engineering Institute, Changchun, 130118, China agaobing0431@126.com, Key Words: Low-alloy Coupled Steel bars; Concretes; Rigidity Model; Crack Opening Model; Abstract.
Introduction It is a future our country development trend to make use of a low metal alloy steel to carry on engineering construction.
This text mainly elaborated to adopt low metal alloy steel and low-carbon steel make into a low metal alloy steel through the even weld double reinforcing bar, pass to experiment analysis, make sure its mechanics and craft function index sign; Use concrete structure design norm as the theory foundation that is analytical and experiments a data, set up lately just degree and crack model formula, provided for the later engineering construction basis.
(11) Conclusion Applying low-alloy steel coupled steel bars saves steel and concrete, not only apply to foundation, work, consolidation of foundation pit, foundation beam, foundation mat, column, pile foundation, bracing of slope, anchor rod of soil stratum and rock, but also apply to irrigation works, road engineering, bridge engineering, etc[4].
