Due to excellent mechanical properties and high working efficiency, FRP sheet has attracted significant attention from the field of strengthening in civil engineering.
Introduction It is well known strengthening technology which improve the fatigue performance and raise the service life of the old structures, is becoming a hot topic in civil engineering.
So the strengthening technology of using FRP sheet has attracted significant attention from the field of strengthening in civil engineering.

This circumstance points out the opportunity of monitoring the performance of civil structures over their operational lives.

The strategies for disaster reduction has been gradually changing from considering hazard-formative factors and engineering defensive measures preferentially to reducing the vulnerability of the system fully.
There are two authoritative specifications which’re Appraisal standard of the civil construction reliability (GB50292-1999) (hereafter referred to as the civil standard)[1] and Appraisal standard of dangerous house identification (JGJ125-99) (hereafter referred to as the dangerous standard)[2].The civil standard provides a direct technical reference for the safety and rational use of the civil construction.
Based on the characteristics of civil building and the development of structural reliability design, "Civil standard" adopts the method which is based on probability theory and the limit state of structure various functional requirements to evaluate as the appraisal basis.
While the qualified rate of project quality has been reached 92%, there are still nearly 1/10 of the engineering to be not qualified.

Utilization of Geosynthetic Material Interfaces for Reduction of Cyclic Motion Induced Accelerations Volkan Kalpakci1, a 1Department of Civil Engineering, Hasan Kalyoncu University, Şahinbey / Gaziantep / Turkey avolkan.kalpakci@hku.edu.tr Keywords: Geosynthetic, geotextile, geomembrane, cyclic, isolation, interface Abstract.
The geosynthetic materials are extensively used in a wide range of applications in civil engineering.
Introduction The use of geosynthetic materials in civil engineering applications has become more and more popular especially during the past few decades.
Conclusions Geosynthetics are recognized as the material of new era in civil engineering applications as it is changing the old fashioned design principles with traditional materials while enabling many different applications.

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.

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].

The fire resistance of concrete filled steel tubular column is usually obtained by the numerical analysis method, which is difficult to operate and not convenient in the actual civil engineering.
It can be seen from comparison that the formula results are reasonable in engineering practices and can meet the requirement of safety and reliability of civil engineering.
