This edition covers the latest changes in UK and international practice, and the design methods described refer to British Standards 8007, 8110 and 8102 as well as US standards (including ACI codes). Reference is also made to the recent Australian standard AS 3735-1991.
A new edition of a successful engineering text that provides an interpretation of the more theoretical guidance given in the new suite of Eurocodes for the subject of retaining structures.
Presents a cohesive and comprehensive understanding of water-retaining structures' construction in order to build with speed and economy. Contains numerous worldwide examples, many of which are based on existing structures as well as extensive tables related to the analysis of rectangular, circular and conical formations in order to develop good working practice. Also features practical diagrams, computer programs, listings and a useful appendix which covers the analysis of ground-supported open circular concrete tanks.
Offers design tables that assist the design process and save time. This book provides calculations of minimum reinforcement, crack spacing, and crack widths in relation to temperature and moisture effects. It also provides calculations of crack widths in mature concrete under structural loading.
Based on the latest version of designing codes both for buildings and bridges (GB50010-2010 and JTG D62-2004), this book starts from steel and concrete materials, whose properties are very important to the mechanical behavior of concrete structural members. Step by step, analysis of reinforced and prestressed concrete members under basic loading types (tension, compression, flexure, shearing and torsion) and environmental actions are introduced. The characteristic of the book that distinguishes it from other textbooks on concrete structures is that more emphasis has been laid on the basic theories of reinforced concrete and the application of the basic theories in design of new structures and analysis of existing structures. Examples and problems in each chapter are carefully designed to cover every important knowledge point. As a basic course for undergraduates majoring in civil engineering, this course is different from either the previously learnt mechanics courses or the design courses to be learnt. Compared with mechanics courses, the basic theories of reinforced concrete structures cannot be solely derived by theoretical analysis. And compared with design courses, this course emphasizes the introduction of basic theories rather than simply being a translation of design specifications. The book will focus on both the theoretical derivations and the engineering practices.
This book provides a comprehensive description of the analysis and design process of some hydraulic concrete structures designed to retain and contain aqueous liquid. The first edition discussed six types of structures of different functions, namely: (a) An underground sedimentation tank for sewage treatment.(b) An underground digestion tank for sludge treatment.(c) An underground reservoir to store fresh potable water.(d) An immersed highway tunnel under the river bed.(e) An indoor swimming pool of rectangular shape for public recreation.(f) A gravity dam across a valley for converting the valley into a fresh water reservoir. This Second Edition incorporates another type of hydraulic structure, namely spillway. The spillway structure plays a vital role in regulating the designed reservoir water level to meet the fluctuating demand of water supply for the generation of hydroelectricity, irrigation and water supply purposes in controlling the height of reservoir water level downstream of the river. The spillway structure subjected to seismic hydrodynamic pressure in addition to the hydrostatic pressure, has been analysed and designed in full compliance with Eurocodes EC 2: Part 1–1 and Part 3 as water-retaining structure. The other six structures have been analysed and designed with reference to the relevant clauses of codes of practice prescribed in Eurocodes 2 and BS 8007 and BS 8110. The book is designed to serve as a useful practical guide and a valuable reference for senior undergraduate students of civil engineering and postgraduate students specializing in structural design, as well as practising and consulting engineers involved in the design and execution of hydraulic concrete structures.
Steel-reinforced concrete is used ubiquitously as a building material due to its unique combination of the high compressive strength of concrete and the high tensile strength of steel. Therefore, reinforced concrete is an ideal composite material that is used for a wide range of applications in structural engineering such as buildings, bridges, tunnels, harbor quays, foundations, tanks and pipes. To ensure durability of these structures, however, measures must be taken to prevent, diagnose and, if necessary, repair damage to the material especially due to corrosion of the steel reinforcement. The book examines the different aspects of corrosion of steel in concrete, starting from basic and essential mechanisms of the phenomenon, moving up to practical consequences for designers, contractors and owners both for new and existing reinforced and prestressed concrete structures. It covers general aspects of corrosion and protection of reinforcement, forms of attack in the presence of carbonation and chlorides, problems of hydrogen embrittlement as well as techniques of diagnosis, monitoring and repair. This second edition updates the contents with recent findings on the different topics considered and bibliographic references, with particular attention to recent European standards. This book is a self-contained treatment for civil and construction engineers, material scientists, advanced students and architects concerned with the design and maintenance of reinforced concrete structures. Readers will benefit from the knowledge, tools, and methods needed to understand corrosion in reinforced concrete and how to prevent it or keep it within acceptable limits.
