Damage to structures due to vibrations from pile driving operations is of great concern to engineers. This research has stemmed from the need to address potential damage to concrete-filled pipe piles and recently placed concrete structures that could be affected by pile driving vibrations. The study will focus on two topics: (1) The attenuation of potentially damaging pile driving vibrations with distance from the source, and (2) The effects of distance and curing time of concrete on the quality (unconfined compressive strength) of recentlyplaced concrete exposed to pile driving vibrations. The effects of pile driving vibrations did not cause problems with concrete compressive strength except for the case where concrete had only cured for 4 to 6 hours before vibration.

This manual provides direction for the preparation of noise and vibration sections of environmental documents for mass transportation projects. The manual has been developed in the interest of promoting quality and uniformity in assessments. It is expected to be used by people associated with or affected by the urban transit industry, including Federal Transit Administration (FTA) staff, grant applicants, consultants and the general public. Each of these groups has an interest in noise/vibration assessment, but not all have the need for all the details of the process. Consequently, this manual has been prepared to serve readers with varying levels of technical background and interests. It sets forth the basic concepts, methods and procedures for documenting the extent and severity of noise impacts from transit projects.

Because environmental acoustics has a complex mathematical basis,it is often difficult to determine whether acousticalrecommendations are valid. Handbook of Environmental Acousticssimplifies this decision-making process and provides easy-to-followexplanations of acoustic terminology, noise control design, andregulatory noise issues. The book clarifies key aspects ofenvironmental noise in basic language, covering: * Common noise sources--including the risk of exposure to commondaily environmental noise sources * Current noise regulations, guidelines, andstandards--illustrating all key points * Acoustic terminology and environmental noisedescriptors--providing a foundation for understanding noiseissues * Effects of noise on people and animals--emphasizing theimportance of restricting noise exposure * Relevant noise rating methods--clarifiying the use of noisemetrics * Construction and building code requirements--explaining currentrequirements and featuring tips on how to avoid privacyproblems * Measurement considerations--demonstrating standard methods andoffering practical advice on how to ensure proper measurementprocedures * Noise control designs--detailing source-path-receiver systems andnoise control fundamentals In addition to traditional noise control methods, new areas, suchas active noise control, sound intensity measurement, and diffusivedesigns, are explained. A sample municipal noise ordinance helpsthe user to draft an ordinance tailored to the needs of aparticular community. Avoiding complex mathematics and analyses,Handbook of Environmental Acoustics is a user-friendly manual forurban planners, municipal officials, engineers, attorneys,industrial hygienists, architects, environmental professionals, andstudents in these fields.

Over the past two decades concrete has enjoyed a renewed level of research and testing, resulting in the development of many new types of concrete. Through the use of various additives, production techniques and chemical processes, there is now a great degree of control over the properties of specific concretes for a wide range of applications. New theories, models and testing techniques have also been developed to push the envelope of concrete as a building material. There is no current textbook which brings all of these advancements together in a single volume. This book aims to bridge the gap between the traditional concrete technologies and the emerging state-of-the-art technologies which are gaining wider use.

Understanding and recognising failure mechanisms in concrete is a fundamental pre-requisite to determining the type of repair, or whether a repair is feasible. This title provides a review of concrete deterioration and damage, as well as looking at the problem of defects in concrete. It also discusses condition assessment and repair techniques.Part one discusses failure mechanisms in concrete and covers topics such as causes and mechanisms of deterioration in reinforced concrete, types of damage in concrete structures, types and causes of cracking and condition assessment of concrete structures. Part two reviews the repair of concrete structures with coverage of themes such as standards and guidelines for repairing concrete structures, methods of crack repair, repair materials, bonded concrete overlays, repairing and retrofitting concrete structures with fiber-reinforced polymers, patching deteriorated concrete structures and durability of repaired concrete.With its distinguished editor and international team of contributors, Failure and repair of concrete structures is a standard reference for civil engineers, architects and anyone working in the construction sector, as well as those concerned with ensuring the safety of concrete structures. - Provides a review of concrete deterioration and damage - Discusses condition assessment and repair techniques, standards and guidelines

This edited volume presents selected contributions from the International Conference on Experimental Vibration Analysis of Civil Engineering Structures held in San Diego, California in 2017 (EVACES2017). The event brought together engineers, scientists, researchers, and practitioners, providing a forum for discussing and disseminating the latest developments and achievements in all major aspects of dynamic testing for civil engineering structures, including instrumentation, sources of excitation, data analysis, system identification, monitoring and condition assessment, in-situ and laboratory experiments, codes and standards, and vibration mitigation.
