Environmental engineering has a leading role in the elimination of ecological threats, and deals, in brief, with securing technically the conditions which create a safe environment for mankind to live in. Due to its interdisciplinary character it can deal with a wide range of technical and technological problems. Since environmental engineering uses the knowledge of the basic sciences – biology, chemistry, biochemistry and physics – it is able to neutralise pollution in all the elements of the environment, i.e. the hydrosphere, atmosphere and lithosphere. Moreover, environmental engineering deals with the design and maintenance of systems of water supply, sewage disposal, heating, ventilation and air-conditioning in buildings.
Environmental Engineering IV contains 77 peer reviewed papers selected from 527 presented at the 4th Congress of Environmental Engineering (Lublin, Poland, 2-5 September 2012). The contributions are divided into 7 chapters:
• Water supply
• Water and wastewater treatment
• Neutralization of solid wastes and sludge
• Air protection and quality
• Indoor microclimate
• Energy
• Biology and technology
Environmental Engineering IV assesses the state of scientific research in various areas of environmental engineering, evaluates the organizational, technical and technological progress made in contributing to ecological security, and determines the place of environmental engineering in sustainable development, taking into account current political and economic conditions, and is a valuable source of information for the environmental engineering professional and academic community.

Structural reliability has become a discipline of international interest, addressing issues such as the safety of buildings, bridges, towers and other structures. This book addresses the important issue of predicting the safety of structures at the design stage and also the safety of existing, perhaps deteriorating structures. Attention is focused on the development and definition of limit states such as serviceability and ultimate strength, the definition of failure and the various models which might be used to describe strength and loading.
Much consideration is given to problem formulation and to the various techniques which can be applied to problem solution. These include the First Order Second Moment method and their derivatives, as well as various Monte Carlo tchniques. Each of these are described in considerable detail and example applications are given. Structural systems are also described, as is the effect of time on reliability estimation, and on the development of design code rules on the basis of limit state principles as under-pinned by probability theory. Furthermore, procedures for the reliability estimation of existing structures are also included.
The book emphasises concepts and applications, built up from basic principles and avoids undue mathematical rigour. It presents an accesible and unified account of the theory and techniques for the analysis of the reliability of engineering structures using probability theory. A balanced view of the subject is offered here not only for newcomers, but also for the more specialist reader, such as senior undergraduate and post-graduate students and practising engineers in civil, structural, geotechnical and mechanical engineering.

Author: Michael R. Horne | Size: 11 MB | Format:PDF | Quality:Scanner | Publisher: PERGAMON INTERNATIONAL LIBRARY | Year: 1979 | pages: 177
"The plastic theory of structures," the author writes, "is an essential complement to elastic theory. The readily applied forms of either theory depend on idealized mathematical models both of the material properties and of the fabricated nature of the structure. By applying each theory in turn to the same structure, a much better overall picture is obtained of the stability, rigidity, and strength than is possible by applying either theory on its own."
Plastic theory is used as the basis of design for the majority of single-story rigid frames and is being increasingly applied to multistory frames. An important feature of the theory is the extent to which intuitive ideas of structural behavior may be used to solve problems. In this text, Professor Horne employs this method to explain the principles involved. He backs up the intuitive approach by formal statements and proofs of theorems and explains the methods of plastic analysis. Methods which are of value in design applications and are suited primarily to hand calculations are emphasized, but methods suitable for computer application are also included. Relevant problems are given at the end of each chapter with answers at the end of the book.

Comparative Study of Methods of Determination of Coefficient of Subgrade Reaction
ABSTRACT
In this paper, different methods proposed for determination of the coefficient of subgrade reaction, ks are discussed, compared and evaluated for their suitability and accuracy. The geotechnical characteristics of a site on Tabriz Marl were selected as the base data and settlement analysis results with different methods were compared with that of obtained from analyses with advanced soil models using Safe and Plaxis software. It was discovered that for Tabriz Marl, soft soil model is the best governing model and Vesic relation among the methods of determination of ks leads to a negligible error in comparison to the soft soil model.
Also, in order to achieve more accurate results from these methods, it is proposed to use mean elasticity modulus which takes into account the effect of geometric and mechanical properties of sub-layers.
KEYWORDS: Winkler model, soft soil model, coefficient of subgrade reaction, modulus of elasticity, settlement.
