This book presents a method for solving linear ordinary differential equations based on the factorization of the differential operator. The approach for the case of constant coefficients is elementary, and only requires a basic knowledge of calculus and linear algebra. In particular, the book avoids the use of distribution theory, as well as the other more advanced approaches: Laplace transform, linear systems, the general theory of linear equations with variable coefficients and variation of parameters. The case of variable coefficients is addressed using Mammana’s result for the factorization of a real linear ordinary differential operator into a product of first-order (complex) factors, as well as a recent generalization of this result to the case of complex-valued coefficients.

Shallow Foundations: Discussions and Problem Solving is written for civil engineers and all civil engineering students taking courses in soil mechanics and geotechnical engineering. It covers the analysis, design and application of shallow foundations, with a primary focus on the interface between the structural elements and underlying soil. Topics such as site investigation, foundation contact pressure and settlement, vertical stresses in soils due to foundation loads, settlements, and bearing capacity are all fully covered, and a chapter is devoted to the structural design of different types of shallow foundations. It provides essential data for the design of shallow foundations under normal circumstances, considering both the American (ACI) and the European (EN) Standard Building Code Requirements, with each chapter being a concise discussion of critical and practical aspects. Applications are highlighted through solving a relatively large number of realistic problems. A total of 180 problems, all with full solutions, consolidate understanding of the fundamental principles and illustrate the design and application of shallow foundations.

The development of the use of polymeric materials in the form of geosynthetics has brought about major changes in the civil engineering industry. Geosynthetics are available in a wide range of compositions appropriate to different applications and environments. Over the past three to four decades, civil engineers have grown increasingly interested in geosynthetics and in understanding their correct use. Simultaneously, significant advances have been made in the use of geosynthetics in civil engineering applications as well as in the areas of aquaculture, agriculture and mining engineering. These developments have occurred because of the ongoing dialogue among leading engineers and researchers from several organizations and academic institutions.
This concise introductory textbook on geosynthetics deals with the basic concepts of the subject, especially for meeting the requirements of senior undergraduate/graduate students as well as of practising engineers who have not been exposed to geosynthetics thus far. It includes recently developed fundamental concepts and new applications covering the use of polymer and other fibres in soil improvement.

The First Southern African Geotechnical Conference was organised by the Geotechnical Division of the South African Institution of Civil Engineering (SAICE) under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) and took place at Sun City, South Africa on 5 and 6 May 2016. More than 60 papers were received from authors in South Africa, Botswana, Kenya, Tanzania, Uganda, Algeria, Austria, France, Germany, Switzerland and the United Kingdom. They represent consulting engineers and engineering geologists, contractors, academics and product specialists. The papers were grouped into the following themes: Foundations, Mining and Tailings, Modelling and Design, Site investigation, Soil Properties and Soil Reinforcement and Slopes.

Recent Progress in Steel and Composite Structures: Proceedings of the XIII International Conference on Metal Structures
Author(s)/Editor(s): Marian A. Gizejowski and Jakub Marcinowski | Size: 216 MB | Format:PDF | Quality:Unspecified | Publisher: CRC PRESS | Year: 2016 | pages: 224 | ISBN: 1138029467
Recent Progress in Steel and Composite Structures includes papers presented at the XIIIth International Conference on Metal Structures (ICMS 2016, Zielona Góra, Poland, 15-17 June 2016). The contributions focus on the progress made in theoretical, numerical and experimental research, with special attention given to new concepts and algorithmic procedures, and to background knowledge as well as the development and implementation of rules and recommendations for codification worldwide.
The keynote contributions are from: (1) J. Michael Rotter (University of Edinburgh, UK), on advances in the shell buckling phenomenon, which is of particular importance for industrial metal structures such as silos, tanks and vessels; (2) Milan Veljkovic (Lulea University, Sweden), on conceptual and design aspects of supporting structures for wind energy generation, which topic is related to the current worldwide discussion on the benefits of wind power in the light of high vulnerability of modern economies to changes in fuel prices and the imminent shortage of fossil resources; (3) Jiang Qian (Tongji Univeresity, China), on advances in seismic assessment and control of steel-concrete composite high-rise buildings; (4) Johan V. Rietief (University of Stellenbosch, South Africa), international efforts to harmonize and unify reliability-based codification within the area of civil engineering structures. Recent developments in metal and steel-concrete composite structures in Poland are summarized in the 5th and final keynote paper by Tomasz Siwowski (Rzeszów University of Technology, Poland) and Krzysztof Żółtowski (Gdańsk University of Technology, Poland), in which they describe advances in modern structural shaping, material engineering and technology, as well as in computation and design, using examples of recent, spectacular bridges and sporting venues in Poland.
In addition to the five keynote papers the book contains 62 two-page extended abstracts of individual contributions delivered by 164 Authors and Co-authors from 13 countries of four continents. The CD containing all full-length papers is an attachment to the conference book. The individual papers cover a wide variety of topics:
-Cold-formed sections and profiled sheeting
- Steel-concrete composite structures
- Buckling and effect of bracings
- Dynamics, fatigue and seismic analyses
- Bridges, Structural steel, metallurgy and behaviour in fire
- Strength, stability and postbuckling behaviour
- Joints and connections
- Silos, tanks and vessels and
- Reliability, masts and towers
Recent Progress in Steel and Composite Structures is a useful reference source to academics, researchers, graduate students and practicing engineers.
