Building Research Establishment ... 68 pages - Publisher: IHS BRE Press; 3rd edition (November, 2010) ... Language: English - ISBN-10: 1860817548 - ISBN-13: 978-1860817540 ...

This BRE Special Digest provides practical guidance on specifying concrete for use in natural ground and in brownfield locations. The procedures for ground assessment and concrete specification cover the fairly common occurrence of sulfates, sulfides and acids and also the more rarely occurring aggressive carbon dioxide found in some ground and surface waters, which affects concrete foundations and sub-structures. This edition has been revised to reflect thinking and changes to British Standards. It introduces the phenomenon of chemical attack of concrete in the ground, describes modes of chemical attack and discusses the mechanisms of the principal types, including sulfate and acid attack, and the action of aggressive carbon dioxide. It then gives guidance on assessing the chemical aggressiveness of the ground, and recommendations for specifying concrete for general cast-in-situ use in the ground. It also gives recommendations for specifying surface carbonated precast concrete for general use in the ground, and includes design guides for specification of specific precast concrete products, including pipeline systems, box culverts and segmental linings for tunnels and shafts. The guidance applies to both buildings and civil engineering construction.

ASDIP CONCRETE contains a COLUMN DESIGN module. Now structural engineers can work cost-effectively to design circular or rectangular concrete columns based upon a combination of biaxial bending moments and axial loading. All software calculations are based upon ACI design criteria and Ultimate Strength Design Method. This structural engineering software calculates magnified moments due to slenderness and generates capacity axial-moment interaction diagram. Input: The required input data is organized on tabbed pages. The column cross-section may be rectangular or circular. The slenderness condition is considered by specifying the effective member length and if the column is sway or non-sway. This structural engineering software utilizes either the actual parabolic concrete stress-strain curve or the simplified equivalent rectangular one. The steel may consider strain hardening region. The loads may be modeled as part of the dead, live, roof live, snow, wind, and seismic load cases. If necessary, the moments are internally magnified and the program combines the loads per specified load combinations. Output: The output results are organized on tabbed pages. This structural engineering software calculates magnified moments and axial loads for all the specified load combinations. The 3D capacity interaction diagram is accurately calculated based on the geometry and reinforcement for biaxial columns. The moment magnification process is detailed and reported for a granular check of the design. The values that fail the design criteria are highlighted in red for easy to identify.

Concrete Beam Design: Beams are structural elements that support loads applied transversely, and therefore they mostly resist bending moments, as well as shear forces. Concrete beams are usually continuous, this is, they span between several supports. A common example of a T-beam occurs at the interior bay of a building floor, where a portion of the slab acts together with the projecting beam web. A beam at the border of the floor is called a spandrel beam. The program performs the design of a multi-span rectangular, T, or inverted-T concrete beam when subjected to a combination of bending and shear loading, based on the latest ACI design criteria and the Ultimate Strength Design Method. Multiple options are included to model the beam geometry and loads, as well as the reinforcing steel. Input: The required input data is organized on tabbed pages at the left half of the screen. The beam cross section may be either rectangular, T, spandrel, inverted-T, or L. A maximum of five spans may be modeled and two cantilevers. The end supports may be either pinned or fixed. This structural engineering software uses either the actual parabolic concrete stress-strain curve, or the simplified equivalent rectangular one. The steel considers the strain hardening region. Distributed and concentrated loads may be modeled as part of the dead, live, roof live, and snow load cases. The program internally combines the applied loads per the specified load combinations. Output: The output results are organized on tabbed pages. This structural engineering software calculates moments and shears along the beam for all the specified load combinations. The capacity is accurately calculated based upon geometry and reinforcement considering the moment gradient due to the development length of all the reinforcing bars. This structural engineering software allows to show the beam per span number and per load combination, for a granular check of the whole design process. The construction graph shows a scaled sketch of the beam elevation with information of the reinforcement.

Concrete Bearing Wall Design: Bearing walls are structural compression members which also may resist out-of-plane lateral loads. The resulting moments are referred to as weak-axis bending. A tilt-up wall panel exposed to wind is an example of this type of wall. Per ACI, bearing walls may be designed as compression members using the strength design provisions for flexure and axial loads, like columns. Any wall may be designed by this method and no minimum wall thicknesses are prescribed. As with columns, the design of walls is difficult without the use of design aids. Wall design is further complicated by the fact that slenderness is a consideration in practically all cases. The ACI Moment Magnification method is generally used to account for the slenderness effects. This structural engineering software performs design of concrete bearing wall when subjected to a combination of weak-axis bending moments and axial loading. All calculations are based upon the latest ACI design criteria and the Ultimate Strength Design Method. This structural engineering software calculates magnified moments due to slenderness and generates the capacity axial-moment interaction diagram. A multi-story wall may also be modeled. Input: The required input data is organized on tabbed pages. The wall section is rectangular with either one or two curtains of reinforcement. A parapet may be specified or the wall may be continuous at top. In this latter case, the load from the upper floor is accounted for by setting the uniform load eccentricity as zero. This structural engineering software uses the actual parabolic concrete stress-strain curve rather than the simplified equivalent rectangular one. The steel considers the strain hardening region. The loads may be modeled as part of the dead, live, roof live, snow, and wind load cases. The moments are internally magnified and the program combines the loads per the specified load combinations. Output: The output results are organized on tabbed pages. This structural engineering software calculates magnified moments and axial loads for all the specified load combinations. The capacity interaction diagram is accurately calculated based on the geometry and reinforcement. The moment magnification process is detailed and reported for a granular check of the design. The values that fail the design criteria are highlighted in red for easy to identify.

Glassfibre reinforced concrete (GRC) is the most complex material widely used in current construction practice. It is an unusual composite, in which both the matrix and the reinforcement themselves are composites. This book provides guidance on the properties, its specification, testing and the latest methods for efficient production. Detailed information is presented about the unique aspects of the internal structure and fracture mechanisms of GRC and how the latest advances in nanotechnology are leading towards a fuller understanding of the rational design of GRC and the potential for further improvement of properties beyond those used in contemporary construction practice.GRC is already firmly established as the high-tech material of choice for architects and designers and recent decades have witnessed a rapid increase in production of GRC world-wide. However, to provide the full picture and encompass the most recent developments in GRC and how it can be exploited in major projects, a substantial part of the book is made up of case studies. GRC has been always a very versatile material; however, its range of practical applications has grown significantly.From small, simple items (flowerpots, drainage channels, window sills, etc. ) to large-scale, high-tech iconic projects from leading architects, where GRC has to cope with the highest demands regarding structural complexity, freedom of shape, striking appearance combined with durability and overall quality and excellent environmental performance. The composite is well used in the reconstruction of complex historic facades and GRC has moved beyond construction into the domain of art and interior decorations and furniture. The case studies show numerous examples of such designs and products, including recently developed large double-curved panels with unusual surfaces and strong colours, and self-cleaning and photocatalytic (air-cleaning) e-GRC.

Practising engineers on site, in the design office or in client organizations will find this book an excellent introduction to the design and construction of sprayed concrete lined (SCL) tunnels. The complex behaviour of the early age behaviour of the sprayed concrete requires careful management. This book covers all aspects of SCL tunnelling – from the constituents of sprayed concrete to detailed design and management during construction. Although there is a close interdependence between all the facets of sprayed concrete, few engineers have the right breadth of experience and expertise, and this urgently needs to be transferred to the wider engineering community. Disseminating essential information for tunnelling engineers, Sprayed Concrete Lined Tunnels is key reading for all involved in or studying the process.

The response of concrete under tensile loading is crucial for most applications because concrete is much weaker in tension than in compression. Understanding the response mechanisms of concrete under tensile conditions is therefore key to understanding and using concrete in structural applications. Understanding the tensile properties of concrete summarises key recent research in this important subject. After an introduction to concrete, the book is divided into two parts: part one on static response and part two on dynamic response. Part one starts with a summary chapter on the most important parameters that affect the tensile response of concrete. Chapters show how multi scale modelling is used to relate concrete composition to tensile properties. Part two focuses on dynamic response and starts with an introduction to the different regimes of dynamic loading, ranging from the low frequency loading by wind or earthquakes up to the extreme dynamic conditions due to explosions and ballistic impacts. Following chapters review dynamic testing techniques and devices that deal with the various regimes of dynamic loading. Later chapters highlight the dynamic behaviour of concrete from different viewpoints, and the book ends with a chapter on practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications. Drawing on the work of some of the leading experts in the field, Understanding the tensile properties of concrete is a valuable reference for civil and structural engineers as well as those researching this important material. Summarises key recent research in the areas of understanding the response mechanisms of concrete under tensile conditions. * Provides a summary of the most important parameters that affect the tensile response of concrete and shows how multi scale modeling is used to relate concrete composition to tensile properties. * Highlights the dynamic behaviour of concrete from different viewpoints and provides practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications.

... Structural engineers must focus on a structure’s continued safety throughout its service life. Reinforced Concrete Structural Reliability covers the methods that enable engineers to keep structures reliable during all project phases, and presents a practical exploration of up-to-date techniques for predicting the lifetime of a structure. The book also helps readers understand where the safety factors used come from and addresses the problems that arise from deviation from these factors. It also examines the question of what code is best to follow for a specific project: the American code, the British Standard, the Eurocode, or other local codes. The author devotes an entire chapter to practical statistics methods and probability theory used in structural and civil engineering, both important for calculating the probability of structural failure (reliability analysis). The text addresses the effects of time, environmental conditions, and loads to assess consequences on older structures as well as to calculate the probability of failure. It also presents the effects of steel bar corrosion and column corrosion, and precautions to consider along with guides for design. This book offers guidelines and tools to evaluate existing as well as new structures, providing all available methods and tests for assessing structures, including visual inspection and nondestructive testing for concrete strength. It also presents techniques for predicting the remaining service life of a structure, which can be used to determine whether to perform repairs or take other action. This practical guide helps readers to differentiate between and understand the philosophy of the various codes and standards, enabling them to work anywhere in the world. It will aid engineers at all levels working on projects from the design to the maintenance phase, increasing their grasp of structure behavior, codes and factors, and predicting service life.
