By the studying, the aim is to improve calculating efficiency for most of engineers and to push forward application of structural reliability theory in geotechnical engineering.
However, the traditional method can not describe and deal with various kinds of non-definitude factors which exist objectively in civil engineering, and it also can not analyze and calculate every indexes of safety and economics, and it also coordinate the contradictions between safety, economics and suiting, and do not balance with them.
And all of methods need to write so complicated program to calculation that to restrain the theory in applying of civil engineering [1-6].
By the studying, the aim is to improve calculating efficiency for most of engineers and to push forward application of structural reliability theory in geotechnical engineering.
So its applying research on these ways will push forward application of engineering optimization design based on theory of reliability in geotechnical engineering.

Throughout our cost filed so far, researchers mostly study quote or management of measure item on valuation and management of engineering project in theory.
According to the composition of engineering quantity list cost, this paper had a descriptive statistic on the collected sample data by the descriptive statistical function of SPSS[1].
Build the Linear regression model of construction measure expense and civil project direct cost, we can also find that the constant testing is not significant after trial calculation.
According to the result of the calculation, regression coefficient is 0.223, confidence interval of 95% is 0.206－0.24, the regression equation of construction measure expense and civil project direct cost is : Construction Measure Expense = Civil Project Direct cost × 22.3%

Experimental Assessment of Structural Control Devices used to Protect Civil Buildings Georges Magonette European Laboratory for Structural Assessment (ELSA) IPSC European Commission - JRC TP 480, Via Fermi 2749, 21027 Ispra, Italy georges.magonette@jrc.it Keywords: Pseudodynamic, substructuring, semiactive devices.
This paper presents the latest developments realized at the European Laboratory for Structural Assessment (ELSA) of the Joint Research Centre (JRC) to extend the 'on-line testing method with substructuring' to the experimental verification of civil buildings protected by semiactive devices.
These factors explain the considerable interest in the practical implementation of these systems for protection of civil infrastructures against earthquake and wind loading or, more generally, for vibration mitigation.

Management Status and Problems of Construction Engineering Cost Index in China Management Status of Construction Engineering Cost Index Although some cities in China advanced in engineering cost management have carried out the engineering cost index compilation and distribution.
The engineering cost index system of Tianjin is shown in Fig.1: Fig.1 Engineering Cost Index System of the City of Tianjin (2)Engineering cost index management situation in Shenzhen In the compilation of domestic engineering cost index, Shenzhen is at a more advanced level, which pays attention to the practical application of engineering cost index.
This advanced management experience can be summarized in the following aspects: (1)Consummate engineering cost index system had been established In United States or Hong Kong, the compilation of engineering cost index is usually divided into two channels, government and civil.
The government released a general, overall cost index information, and civil organizations released cost index information of related resources[5].

Effect of Metashaleas SCM on Mechanical and Thermal Properties in Concrete Production Dana Koňákováa *, Eva Vejmelkováb Department of Materials Engineering and Chemistry, Faculty of Civil Engineering, Czech Technical University in Prague, Thákurova 7, 166 29 Praha 6, Czech Republic adana.konakova@fsv.cvut.cz,beva.vejmelkova@fsv.cvut.cz Keywords: Concrete, Burnt shale, Basic physical properties, Compressive strength, Thermal conductivity Abstract.
However all studied materials shows appropriate properties to be applicable in civil engineering branch as load-bearing concrete.
Also in civil engineering branch this question leads to new perspective on building materials.
Concrete can be considered as the main material in civil engineering, and one of its main components is cement.Production of cement is not only energy intensive but it is also one of the main CO2 emission source in the world.
Anyhow all studied materials shows appropriate properties to be applicable in civil engineering branch as load-bearing concrete.
