The Application of the Complete Decomposition Model in Analyzing the Incontrollable Construction Cost FANG Li1, a, MA Xin2,b 1 Economy and management institute, Tongji University, Shanghai 200092, China 2School of Civil Engineering, Chang’ an University, Xi’an 710061, China afangli0601@gmail.com, bmin1016xin@sohu.com Keywords: Civil engineering.
To illustrate, the decomposition on construction cost changes of a small civil project is carried out.
And the direct engineering cost is the sum of the aggregate prices of subentry engineering.
(17) To the whole direct engineering cost, the change of branch engineering is: (18) In the index form, then: (19) (20) A Case Study There is one small civil project whose settlement exceeded the budget significantly.
For each branch engineering, the foundation engineering, the concrete and reinforced concrete engineering and the earth and rock engineering contribute more than 90% of the exceeding budget; as well as the flooring engineering and the wall and cylindrical engineering also play an positive part in exceeding budget.

This paper presents an analysis about principle of an inertial navigation system (INS) and design an new mechanical architecture of INS in terms of increased availability of GPS for civil aviation.
This new mechanical architecture has a good mechanical properties in mechanical engineering of civil aviation.
So in this paper we design a new mechanical architecture of INS to meet the demands of civil aviation.
Mechanical Architecture of Inertial Navigation System under PBN Mechanical properties of the New INS Because we use the laser gyroscopes in the new system, there are many mechanical properties to meet the demand in mechanical engineering of civil aviation.
This system can meet the requirement in mechanical engineering of civil aviation.

Structural Modal Parameter Identification Based on Natural Excitation Technique Qiang Pei 1,a, Long Li 1,b 1Research ＆ Development Center of Civil Engineering Technology, Dalian University, Dalian 116622, China apqiem@163.com, bdxl269@163.com Keywords: natural excitation technique; structural modal parameter identification; structural engineering Abstract.
Natural excitation technique has found an increasingly wide utilization in civil engineering field.
Civil engineering technology has entered the high-speed development period as well[1].
Then it was gradually applied in the field of civil engineering and has a wide range of development.
But they all meet the engineering requirements.

Recently, the safety of existing civil engineering structures attracts more and more attention.
The long-term strength of concrete plays a key role during the assessment of safety and durability for civil engineering structures.
The strength of concrete will gradually decrease during the service of civil engineering structures.
Introduction As the development of economy, the safety of civil engineering structure has received more and more attention.
For ensuring the safety of civil engineering structure, the condition assessment periodically is needed.

Whether it is international or domestic at present, people’s study on the claim more concentrate on the civil engineering claims.
When claim incident occurs in mechanical and electrical engineering project, people just put the theory and experience of claim in civil engineering project into simple use.
It can solve some problems of mechanical and electrical engineering projects in the contract, but there is great limitation, because there are very big differences between the civil engineering projects and large mechanical and electrical engineering project itself.
First, the majority of the objects of claim study in civil engineering project are the claims of project contractors to owners, which is just the opposite to the objects in this article (the object of our study is that the owners of large engineering project claims contractor); although some documents of studies on the engineering project claim also discuss the claims of owners to the contractors, often there is not a thorough study of this phenomenon, attached to the claims of the contractors to owners.
In the research on the theory and method of owners claim in electromechanical project, although China is still in the level of case analysis and the qualitative analysis, with no systematic theoretical research, and draw lessons from civil engineering claim theory and experience; However, there are still some successful examples, which has accumulated some beneficial experience.

In this study, PZT powder mixed with cement and sand, which is more realistic in civil engineering applications.
Through a series of MTS compression tests, feasibility of using cement-sand based PZT composite materials in civil engineering is evaluated.
Innovative materials such as PZT composite have been studied by many researchers with the intention to develop smart structures in civil engineering.
The studies of the applications for the piezoelectric materials in civil engineering have been done as well.

Taking a low-pylon cable-stayed bridge as engineering background, control indexes in design of bridge were studied[1].
Overall force calculation and later checking research is analysed by the finite element analysis software MIDAS Civil.
Engineering situation The total length of the bridge is 120m+120m, the prestressed concrete girder uses variable cross-section.

How were them built, and how were adjusted to fit their valley environment are interesting questions for each sight-seer, archetects and engineers.
The analysis may be helpful for architects and engineers in design practise.
As the case stands, Tulou was built with skillful concept design during the long-term developing of civil engineering technology and experienced in practical anti-seismic methods. the structure fits to local conditions, local materials, and was benefit to environmental protection and energy saving.

Analysis of structure technology and sports buildings design factors Xiaojie Chen Sichuan College of Architectural Technology, Deyang, Sichuan, 618000, China Pistonengine@163.com Keywords: Structure, Civil, Development, Sports, Analysis Abstract.
Sports building are different from the common civil buildings, which are characterized by strong professional, high technical requirements, especially in large scale, complex function of large-scale comprehensive stadium, frequently become the latest technology, strong ability of science and technology places.
At the same time, structural engineering, material engineering, ecology and intelligence information and other scientific and technological achievements to provide a great degree of freedom and comprehensive technical support for the development of sports buildings, this also fully annotated sports material and cultural attribute of buildings.
The development of sports building structure technology The structure of sports building technology not only associated with the degree of construction is far greater than the general civil construction, but many professional involved in sports architecture project, its interaction with the architecture is significantly higher than other professional.
Bearing structure of these two buildings due to the use of the coffered ceiling, its weight is reduced, the famous Italy architect, engineer Nervi most of the shell structure works by its impact.
