PRACTICAL GUIDE TO DIAGNOSING STRUCTURAL MOVEMENT IN BUILDINGS Concise and readable practitioner focused guide to diagnosing the causes of cracks and movement in buildings The expanded and updated Second Edition of Practical Guide to Diagnosing Structural Movement in Buildings shows how movement can manifest as cracking in the building fabric and provides a rigorous, structured approach to understanding the evidence to ensure the surveyor can confidently diagnose the cause and impact of any structural movement they encounter. The book is written in four parts, with part one describing the key principles of movement and cracking. Parts two and three describe the main features of common forms of movement and the associated crack patterns, with part two covering causes other than ground or foundation movement and part three covering movement caused by ground or foundations. Part four briefly describes the techniques used to arrest further movement or repair damage caused by movement. Topics covered in Practical Guide to Diagnosing Structural Movement in Buildings include: First principles, including crack patterns and cracks, rotational movement, weak routes, load distribution, and movement and orientation Expansion cracking, cavity wall tie corrosion, roof spread, springing from deflected beams, and overloaded floors and beams Clay heave, uneven loading, eccentric loading on foundations, drains and drain trenches, differential foundation movement, and load concentrations on foundations Repair methods, including stitching in brickwork, reinforcing brick mortar joints, tie bars, restraint straps, underpinning, grouting, and root barriers Primarily intended for the relatively inexperienced surveyor or engineer, as well as undergraduate students, Practical Guide to Diagnosing Structural Movement in Buildings focuses on identification and diagnosis, helping to correctly diagnose problems while also demonstrating a methodical approach to show and record how the diagnosis was reached, which is critical in client satisfaction.

"What's the Crack?" When cracking is observed in a building the most common reaction is that it must be the foundations and that it must be serious. Many surveyors are nervous about diagnosing cracks. This is understandable, as the interpretation of cracks can be difficult to teach, with university courses providing little or no time for field experience. Yet by understanding one straightforward principle the majority of cracks can be diagnosed in just a few minutes. Linking this with a good knowledge of construction techniques, the factors that distort cracking patterns and the key features of common causes of cracking, almost all cracks can be diagnosed quickly and with confidence. Practical Guide to Diagnosing Structural Movement in Buildings provides a methodology by which cracks and movement in buildings can be diagnosed. Written in four parts, part one describes the key principles of movement and cracking. Parts two and three describe the main features of common forms of movement and the associated crack patterns. Part two covers causes other than ground or foundation movement and part three covers movement caused by ground or foundation problems. Part four briefly describes the techniques used to arrest further movement or repair damage cause by movement. Primarily intended for the relatively inexperienced surveyor or engineer and undergraduate students of surveying as a practical guide for use on site, it focuses on identification and diagnosis. It will not only help in correctly diagnosing the problem but it will also demonstrate a methodical approach to show and record how the diagnosis was reached – critical when giving advice to third parties. "What's the crack?" - In the vast majority of cases it's not foundation related and in most cases it's not indicating a serious defect.

In recent years building failures and the resulting lawsuits and awards for damages have frequently been in the news. The biggest headlines may have been reserved for structural failures and complete collapses, but we should not forget the less newsworthy failures such as leaky roofs, damp walls, dropped foundations and rotted timber. This book gives practical guidance on the prevention of failure by describing the nature and cause of the most common defects in buildings, and then shows how they should be avoided in design and construction.

In Structural Condition Assessment, editor-in-chief Robert T. Ratay gathers together the leading people in the field to produce the first unified resource on all aspects of structural condition assessment for strength, serviceability, restoration, adaptive reuse, code compliance, and vulnerability. Organized by the four main stages of a structural evaluation, this book provides an introduction to structural deterioration and its consequences, the business and legal aspects of conducting an evaluation, initial survey and evaluation techniques for various structures, and specific tests for five of the most common structural materials (concrete, steel, masonry, timber and fabric.)

Mit Hilfe der Statikanalyse wird der Zustand der Bausubstanz und Konstruktionssysteme eines Bauwerkes untersucht. Wenn Probleme am Bauwerk entstehen, führen Statiker eine solche Analyse durch, um die am besten geeigneten Korrekturmöglichkeiten zu bestimmen. Auch Architekten müssen über Grundkenntnisse in der Baustatik verfügen, um Gebäude entwerfen zu können, die ihre Funktion optimal erfüllen und um mit anderen Kollegen des Bauteams effektiv zusammenzuarbeiten. Außerdem müssen Architekten in der Lage sein, selbst eine Statikanalyse durchzuführen, wenn sie ein vorhandenes Gebäude umbauen wollen. Dieses Buch ist ein wichtiges Nachschlagewerk für jeden, der historische Bauten umbauen und verändern will. Es ist darüber hinaus ein nützlicher Leitfaden zu technischen Daten und Berechnungsmethoden, die den Architekten und Statikern damals zur Verfügung standen, als das Baumaterial oder Konstruktionssystem eingesetzt wurde. Mit einer Fülle praktischer Informationen bietet es die Grundlage für moderne Zertifizierung durch den Experten.

Building pathology provides an interdisciplinary approach to the study of defects and performance in order to develop appropriate remedial and management solutions. It considers how the structure and materials of a building relate to its environment, its occupants and the way the building is used, so as to develop a better understanding of building failures. This book provides a well illustrated introduction to the discipline of building pathology, bridging the gap between current approaches to the surveying of buildings and the detailed study of defect diagnosis, prognosis and remediation. It features a number of case studies and a detailed set of references and further reading. This second edition has been updated to reflect changes in legislation, guidance and construction, and provides new case studies that demonstrate the breadth and depth of the subject.

Make any renovation job go smoother. Building renovation, conservation and reuse represents more than half of all construction work - and is projected to increase to 80% by 2004. Structural Renovation of Buildings, by Alexander Newman, puts a single, convenient source of information about all aspects of structural renovation and strengthening of buildings at your fingertips. While its focus is largely on low and midrise buildings, you can apply the principles it clarifies to buildings of any size - steel-framed, masonry, or wood. Whether you're repairing deteriorated concrete...rehabilitating slabs on grade...strengthening lateral-load resisting systems...renovating a building facade...handling seismic upgrades or fire damage, you'll find this time-and-trouble-saving guide loaded with practical tips, methods, and design examples. It's also heavily illustrated with autoCAD generated details, supplier illustrations of materials, procedural techniques, and much, much more.

Providing practical guidance for homeowners whose properties have been affected by subsidence, or heave, or who are concerned by the potential risk of damage, this second edition has been expanded to include sections on other types of subsidence and causes of damage that are unrelated to foundation movement.

From parking garages to roads and bridges, to structural concrete, this comprehensive book describes the causes, effects and remedies for concrete wear and failure. Hundreds of clear illustrations show users how to analyze, repair, clean and maintain concrete structures for optimal performance and cost effectiveness. This book is an invaluable reference for planning jobs, selecting materials, and training employees. With information organized in all-inclusive units for easy reference, this book is ideal for concrete specialists, general contractors, facility managers, civil and structural engineers, and architects.

Observers are digital algorithms that combine sensor outputs with knowledge of the system to provide results superior to traditional structures, which rely wholly on sensors. Observers have been used in selected industries for years, but most books explain them with complex mathematics. Observers in Control Systems uses intuitive discussion, software experiments, and supporting analysis to explain the advantages and disadvantages of observers. If you are working in controls and want to improve your control systems, observers could be the technology you need and this book will give you a clear, thorough explanation of how they work and how to use them. Control systems and devices have become the most essential part of nearly all mechanical systems, machines, devices and manufacturing systems throughout the world. Increasingly the efficiency of production, the reliability of output and increased energy savings are a direct result of the quality and deployment of the control system. A modern and essential tool within the engineer's kit is the Observer which helps improve the performance and reduce the cost of these systems. George Ellis is the author of the highly successful Control System Design Guide (Second Edition). Unlike most controls books, which are written by control theorists and academics, Ellis is a leading engineer, designer, author and lecturer working in industry directly with the users of industrial motion control systems. Observers in Control Systems is written for all professional engineers and is designed to be utilized without an in-depth background in control theory. This is a "real-world" book which will demonstrate how observers work and how they can improve your control system. It also shows how observers operate when conditions are not ideal and teaches the reader how to quickly tune an observer in a working system. Software Available online: A free updated and enhanced version of the author's popular Visual ModelQ allows the reader to practice the concepts with Visual ModelQ models on a PC. Based on a virtual laboratory, all key topics are demonstrated with more than twenty control system models. The models are written in Visual ModelQ ,and are available on the Internet to every reader with a PC. - Teaches observers and Kalman filters from an intuitive perspective - Explains how to reduce control system susceptibility to noise - Shows how to design an adaptive controller based on estimating parameter variation using observers - Shows how to improve a control system's ability to reject disturbances - Key topics are demonstrated with PC-based models of control systems. The models are written in both MatLab® and ModelQ; models are available free of charge
