It is used in a broad range of applications, for instance in automotive industries, fabrication of electrical accessories, civil engineering, and medicine.

Nonlinear static analysis of this structure under rare earthquake can reveal it’s ability to resist lateral force, the distribution and the appearance sequence of plastic hinges, can show the weak links, and based on these, we can evaluates its seismic behavior, and the evaluation can provide theoretical basis for the practical engineering.

Optimization of Polymer-Cement Coating Composition using Material Model Czarnecki Lecha, Sokołowska Joanna Juliab Warsaw University of Technology, Department of Building Material Engineering, Warsaw, Poland al.czarnecki@il.pw.edu.pl, bj.sokolowska@il.pw.edu.pl Keywords: optimization. material model. polymer-cement composite. polymer-cement coating. insulation.
Introduction Polymeric materials have already been used for several years but recently are present in nearly every branch of civil engineering due to their specific properties.
Considering the mathematics – such result is correct but considering the technical properties – it is necessary to find the extremum that would be correct and rational in an “engineering” sense.

According to zone classification for thermal engineering design in “Thermal Engineering Design Standard for Civil Building (GB 50176-93)”, Shenzhen is in the South Zone of the Hot Summer and Warm Winter climate zone.
Therefore, the thermal engineering in Shenzhen area is mainly designed for thermal insulation in the summer instead of warm-keeping in the winter.

Model Experimental Study on Stratified Air Distribution with 2D-PIV for High Ceiling Industrial Plant Jian Shen1,a, Angui Li1,b, Yujiao Zhao 1,c 1School of Environmental and Municipal Engineering, Xi’an University of Architecture and Technology, Xi’an, P.R.
Introduction Nowadays, high ceiling buildings have been appeared increasingly in the industrial and civil occasions.
With reference to the previous studies [1] and in consideration of PIV condition, we finally decide that the model size is 1/50 of the real one based on engineering experiences of past years.
Experimental facility layout Engineering models are usually used to study complex fluid dynamics problems where calculations and computer simulations are not reliable.

The article presents the physical-chemical bases and as result – the technological bases of concrete resistance to ultra-low cryogenic (up to -196 °C) technical (engineering) temperatures, which is applied to the reinforced concrete structures of engineering constructions such as storage tanks for liquefied gases (in particular, liquid nitrogen and oxygen with cryogenic temperatures), as well as the enclosing structures of blocks (units) for air separation for various inert gases.
The latter are necessary for the calculation and design of reinforced concrete structures of engineering constructions operated under the influence of cryogenic technical temperatures.
The researches were carried out in relation to the operating conditions of reinforced concrete structures of such engineering structures as isothermal storage tanks for liquefied natural gases, as well as air separation blocks.
The results of the performed investigations can be used in the calculation of reinforced concrete structures and the design of engineering constructions, which are operated in the conditions of the exposure of extremely low technological temperatures.
