Nonlinear Dynamics of Structures Under Extreme Transient Loads
Covers model building for different engineering structures and provides detailed presentations of extreme loading conditions. A number of illustrations are given quantifying; a plane crash or explosion induced impact loading, the effects of strong earthquake motion, and the impact and long-duration effects of strong stormy winds—along with a relevant framework for using modern computational tools. The book considers the levels of reserve in existing structures, and ways of reducing the negative impact of high-risk situations by employing sounder design procedures.
Modernisation, Mechanisation and Industrialisation of Concrete Structures

Integral waterproofing of concrete structures : Advanced protection technologies of concrete by pore blocking and lining
This book first establishes a background about concrete structures and porosity linked with concrete hydration, then goes on to consider concrete durability problems from the perspective of water penetration including damages from freeze-thaw cycles, alkali silica reactions, and chloride ion penetration. The mechanisms, applications, performances, and limitations of waterproofing technologies including coatings and integral systems are compared. The book also showcases all application methods of crystallization waterproofing materials, including material spray on cured concrete and on fresh concrete, and their addition to concrete mix designs as enhancers or admixtures.

Particular attention is paid to ensuring the early strengthening of concrete within 24 hours after casting and to constructing structures with limited energy resources at the site.
Finite Elements in Structural Analysis : Theoretical Concepts and Modeling Procedures in Statics and Dynamics of Structures
Introduces the basic concepts of the finite element method in the static and dynamic analysis of beam, plate, shell and solid structures, discussing how the method works, the characteristics of a finite element approximation and how to avoid the pitfalls of finite element modeling. Presenting the finite element theory as simply as possible, the book allows readers to gain the knowledge required when applying powerful FEA software tools. Further, it describes modeling procedures, especially for reinforced concrete structures, as well as structural dynamics methods, with a particular focus on the seismic analysis of buildings, and explores the modeling of dynamic systems. Featuring numerous illustrative examples, the book allows readers to easily grasp the fundamentals of the finite element theory and to apply the finite element method proficiently.
Finite element design of concrete structures : Practical problems and their solutions
In Finite Element Design of Concrete Structures: practical problems and their solutions the author addresses this 'blind belief' in computer results by offering a useful critique that 'important details are overlooked due to the flood of information' from the output of computer calculations. Indeed, errors in the numerical model may lead in extreme cases to structural failures as the collapse of the so-called Sleipner platform has demonstrated.
Failures in concrete structures : Case studies in reinforced and prestressed concrete
This selection of the author’s firsthand experience with incidents with RC and prestressed structures helps readers avoid the same errors—mistakes discovered at the design stage, or that led to failures or partial structure collapse. It focuses on misunderstanding of structures or codes of practice and specifics during construction.
Electrochemical processes and corrosion in reinforced concrete
Some reinforced concrete structures prematurely corrode as they age, with significant financial implications, but it is not immediately clear why some are more durable than others. This book looks at the various mechanisms for corrosion and how what seemed to be a relatively simple matter has become more complex the further it is understood due to the properties of concrete, steel and the way reinforced concrete structures are constructed. The significance of electrochemical processes is identified with recent research using new technology discussed.
Elasto-plastic damage behaviour of concrete elements
Shows how the mechanical phenomena of familiar concrete structures can be expressed using mathematical models and provides a solid basic understanding of the nonlinear behaviour of concrete structures. It applies elasto-plastic theory to damage mechanics and the modelling of cracks in concrete. Sets out the reality of damage mechanics in concrete Connects standard theory with good design and construction practice
Durability of reinforced concrete structures
Reinforced concrete structures corrode as they age, with significant financial implications, but it is not immediately clear why some are more durable than others. This book looks at the mechanisms for corrosion and how corrosion engineering can be used for these problems to be minimized in future projects. Several different examples of reinforced concrete structures with corrosion problems are described and the various life enhancement solutions considered and applied are discussed. The book includes a chapter on the effectiveness of corrosion monitoring techniques and questions why the reality is at odds with current theory and standards.
Designers' guide to EN1991-1-2, EN1992-1-2, EN1993-1-2 and EN1994-1-2 : Handbook for the fire design of steel, composite and concrete structures to the Eurocodes
The nature of the loading must first be understood before applying the structural engineering principles set out in the Eurocodes. For this reason this book is meant as a guide to four separate documents, EN1991 Part 1.2, EN1992 Part 1.2, EN1993 Part 1.2 and EN1994 Part 1.2 with reference where appropriate to the Eurocode covering the basis of design, EC06.
Designers' guide to EN 1992-2 Eurocode 2 : Design of concrete structures : Part 2: Concrete bridges
Describes the principles and requirements for safety, serviceability and durability of concrete bridges. It provides the user with guidance on the interpretation and use of EN 1992-2 and the relevant provisions of the general rules ofEN 1992-1-1. Worked examples are provided to illustrate the use of the rules. It also explains the relationship with the other Eurocode parts to which if refers (ENs 1990, 1991).
Design of steel-concrete composite structures using high-strength materials
Design of Steel-Concrete Composite Structures Using High Strength Materials provides guidance on the design of composite steel-concrete structures using combined high-strength concretes and steels. The book includes a database of over 2,500 test results on composite columns to evaluate design methods, and presents calculations to determine critical parameters affecting the strength and ductility of high-strength composite columns. Finally, the book proposes design methods for axial-moment interaction curves in composite columns. This allows a unified approach to the design of columns with normal- and high-strength steel concrete materials.

It explains force transfer mechanisms of steel profiles and oncrete interfaces, and an analysis of the characteristics of hybrid structures, including slendercomponents.

The transition zones in partly reinforced concrete and partly composite columns are also covered.

Provides guidelines which can extend the existing standards and codes to cover these types of special works, especially those which are massive in nature, taking account of their specific behaviour in terms of cracking and shrinkage together with other important properties such as water/air leak tightness
Concrete structures deteriorated by delayed ettringite formation and alkali-silica reactions
Discusses the behaviour of isolated concrete bottle-shaped struts affected by internal expansion reactions (ISR). For that purpose, the numerical modelling of damaged concrete was performed using the Concrete Damaged Plasticity Model (CDPM) implemented in ABAQUS and validated the model through Sankovich's tests.
