Introduction Modern engineering structures are developing in a trend of being large and complex.
SHM systems have been successfully used in many types of civil engineering structures, especially in long-term SHM system, providing direct, full and accurate information in structural safty evaluation.
But there are some main problems in such method when applied in civil engineering: Model error is large; environmental factors influence much; the statistic is incomplete; the sensitivity of dynamic characteristics is fairly low; damage identification method is not perfect.
Furthermore, being the simplest, most economical, most practical, and most available modal factor in aspect of economy, frequency has been successfully applied in engineering.
For close complicated and large-scale engineering structure, such change is so small that it is not worth noticing.

The stress and strain must be modified to true stress and true strain using the following equation [11]: True stress, (1) True strain, (2) The different of engineering and true stress - strain diagram for web and flange element as shows in Figure 2 (a) and (b).
The true stress-strain graph is higher than the engineering stress-strain due to reduce in an area and elongation of the gauge length.
Thanks also extend to Faculty of Civil Engineering for providing machinery and equipment.

Study on Damage Parameters and Its Size Effect of Concrete by Tension Test Wang Xiangdong1a；Wang Yuefeng1b；Wang Yan1；Wu Yongjin1；Hua xi1 1Department of Engineering Mechanics, Hohai Univ., Nanjing 210098, China awwang90@sohu.com, bwyf20054005@qq.com Key words: concrete; tension; damage; size effect; damage parameters Abstract.
Introduction Concrete is one of the most important materials in contemporary civil engineering，which is widely used in civil engineering, hydraulic engineering and other fields[1].
It’s well known that damage of concrete results in the degradation of the concrete property in concrete structure, which plays an important role in mechanics and actual engineering [3].

Information technologies in view of complex solution of waste water problems Elena Gogina 1, a, Nikolay Makisha 2, b 1 Professor of the department of waste water treatment and aquatic ecology, Moscow state university of civil engineering, 129337, Russia, Moscow, Yaroslavskoye av.26 2 Associate prof., director of education and research centre “Water supply and waste water treatment”, Moscow state university of civil engineering, 129337, Russia, Moscow, Yaroslavskoye av.26 a goginaes@mgsu.ru, b makishana@mgsu.ru Keywords: sewage system, waste water treatment plant, comprehensive approach, reconstruction Abstract: The article reveals unsatisfactory condition of contemporary sewage systems and structures and contains analyses of modern approaches to design, construction, reconstruction and service of such systems.
Engineering systems of sewage can be divided into two parts – internal and external, that includes sewage network, pumping stations, treatment plants and discharges into the water bodies.
For example, design engineer when choosing pumping equipment should take into account not only certain head and flow rate but also an operation and incoming flow mode for the treatment plant on which waste water is pumped.
That will allow us: - To consider both technical and technological parameters; - To make the maintenance easier due to its’ automation - To interlink engineering systems with geoinformation systems.
