To reduce the environmental impact of civil engineering, priority should be given to preserving existing structures, even if they require repair or significant retrofitting, or at least reusing their components..
Civil engineering has one of the most significant impacts on the environment.
In the field of civil engineering, numerous documents have been created with the aim of introducing fundamental transformations regarding environmental impact.
A brief overview of the most efficient engineering tools is presented below.
However, these materials, due to their widespread availability, durability, economic considerations, and significant potential for environmental improvement, can have the greatest impact on shaping global climate policy in the civil engineering field.

Microstructure of Unburned Clay and Its Shrinkage During Drying OTCOVSKA Tereza1,a *, PADEVET Pavel1,b 1CTU in Prague, Faculty of Civil Engineering, Department of Mechanics, Thakurova 7, Prague 6, Czech Republic atereza.otcovska@fsv.cvut.cz, bpavel.padevet@fsv.cvut.cz Keywords: shrinkage, unburned clay, clay mineral, sand, drying Abstract.
Unburned clay was used for the traditional engineering works for thousands years.
The basic problem that should be mitigated by civil engineers handling unburned clay is its considerable shrinkage during drying.
Sustainable civil engineering could be described as the principles that lead to reducing the impact of building industry on environment.

For the reason of clear conception and simple physical meaning, Duncan-Chang is applied widely in civil engineering field.
Introduction The studied civil constitutive can be divided into two classes: the elastic model and the elastic-plastic model.
The elastic model, such as Duncan-chang model and model, is easy and has been widely applied in engineering calculation.
Conclusions Duncan-chang model has been applied widely in civil engineering field for the reason of clear conception and simple physical meaning.

Both scientific and practical knowledge in the field of civil engineering industry and related topics are presented.

Analysis on Whole Life Cycle Cost Management of Highway Engineering Huihong Fenga, Xiaoping Dingb, Jingsi Chenc and Yu Chend School of Civil Engineering and Architecture, Southwest Petroleum University, Chengdu, Sichuan, 610500, China afenghh163@163.com, bdingxiaopingshu@163.com, csummer68123@126.com d694595905@qq.com Keywords: Highway Engineering, the Whole Life Cycle, Engineering Cost Management.
According to the analysis of the current problems in highway engineering cost management, this paper puts forward the idea of the whole life cycle cost management in highway engineering, and elaborates the specific contents and the control methods of engineering cost management for all stages in the construction process.
Therefore, it must run through the project life cycle that the highway engineering cost management to effectively control the engineering cost, and to achieve good investment returns.
Thus the engineering cost will lose control finally.
Secondly, it should to use value engineering to optimize the design scheme.

Analysis of Seismic Response for an Extradosed Cable-Stayed Curved Bridge Based on Different Design Parameters Hao Su LIU1, a, Jun DONG1, a, Yun YANG2, a, Jin Qiao GAO1, a 1School of Civil Engineering and Traffic Engineering, Beijing University of Civil Engineering and Architecture, Beijing, 100044, P.R.
Since the earthquake response spectrum data from National seismic code in 2008 and with the CQC vibration mode combination method, the diversified models are built by Midas/civil so as to explore the earthquake response mechanism under different design parameters.
The conclusion is the important reference for practical engineering and providing basis for seismic design parameters, but also for seismic design and construction in extradosed cable-stayed curved bridges.
Based on above background, numerical simulations of dynamic response of the bridge have been done by means of FEM Midas/civil software, in which the spatial beam elements should be chosen for the simulation of girder, pylon and pier and space truss units are to the cables.
