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.

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.

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.

Abstract.Using software builds a three-dimension simulation model of the TPS power supplies cable engineering.
The civil engineering of TPS (Taiwan Photon Source) will soon be completed.
The power supply cables engineering should be done before the scheduled completion of the civil engineering.
We use the two-dimensional construction graph to implement all cables for the TPS cable engineering.
We use the two-dimensional construction graph to implement all cables for the TPS cabling engineering [9, 10].

In view of this, in this paper, the application of BIM technology in building water supply and drainage engineering design, as well as the present problems of the BIM are analyzed. 1 Introduction The Chinese full name of BIM is building information modeling.It is based on the three-dimensional digital technology, the integration of all kinds of information related to construction engineering project engineering data modeling, It has five major characteristics including of visualization, optimization, simulation, coordination, can figure out.
Therefore, there will be a large part of civil engineering construction losses in construction projects to communicate information on sharing.
For example, in the building water supply and drainage lately designing, the change of the layout will cause the change of the quantity of the fire hydrant, sprinkler and other fire fighting equipment, the material in the table can be updated in real time, thus greatly improve the design quality and design efficiency. 2.3 Visual design Under the mode of traditional architectural water supply and drainage engineering design, the main data is from the civil engineering CAD platform, applying the view of flat, vertical and cutting to express and display.

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.
