Anisotropic Elasticity - Theory and Applications

Publisher Comments:
Anisotropic Elasticity offers for the first time a comprehensive survey of the analysis of anisotropic materials that can have up to twenty-one elastic constants. Focusing on the mathematically elegant and technically powerful Stroh formalism as a means to understanding the subject, the author tackles a broad range of key topics, including antiplane deformations, Green's functions, stress singularities in composite materials, elliptic inclusions, cracks, thermo-elasticity, and piezoelectric materials, among many others. Well written, theoretically rigorous, and practically oriented, the book will be welcomed by students and researchers alike.
Book News Annotation:
A presentation of two-dimensional deformations of anisotropic elastic solids employing the Stroh formalism and avoiding complicated theory and analysis. Ting (applied mechanics, U. of Illinois) demonstrates: matrix algebra, linear anistropic elastic materials, antiplane deformations, the Lekhnitskii formalism, transformation of matrices, infinite space, stress decay, steady state motion and surface waves, the generalization of the Stroh formalism, and three-dimensional deformations.

Synopsis:
Elasticity is a property of materials which returns them to their original shape after forces applied to change the shape have been removed. This advanced text explores the problems of composite or anisotropic materials and their elasticity.

ACI 223 R-10 Guide for the Use of Shrinkage-Compensating Concrete

Recommendations of this guide include proportioning, mixing, placing, finishing, curing, and testing. Shrinkagecompensating concrete is produced using expansive cements or expansive component systems.
There have been significant changes and advances in the use of shrinkage-compensating concrete since it was first introduced into the market but, in some areas, the original practices remain the best current practice. Although many references used in this guide are over 10 years old, they remain a valid reference to today’s practice.

Performance of Physical Structures in Hurricane Katrina and Hurricane Rita: A Reconnaissance Report

This is the final report on the National Institute of Standards and Technology (NIST) led-reconnaissance to assess the performance of physical structures during Hurricane Katrina and Hurricane Rita. The report describes the environmental conditions (wind speed, storm surge, and flooding) that were present during the hurricanes in regions that were affected by the hurricanes. The report further documents the NIST-led team’s observations of damage to major buildings, infrastructure, and residential structures resulting from wind and wind-borne debris, storm surge, surge-borne debris, and surge-induced flooding. Following Hurricane Katrina’s landfall on August 29, 2005, NIST began planning for a two-phase reconnaissance to study and document damage to major buildings, infrastructure, and residential structures. In phase 1, NIST deployed a roofing expert with a team assembled by the Roofing Industry Committee on Weathering Issues (RICOWI) during the week of September 6, 2005 to study damage to roofing systems in Mississippi Gulf Coast region. NIST deployed four structural engineers in cooperation with the FEMA Mitigation Assessment Team (MAT) during the week of September 26, 2005 to study damage in the Mississippi Gulf Coast region. Two NIST members of this team also inspected the breaches in the floodwalls and levees, as well as damage to major buildings, in New Orleans. These phase 1 deployments provided input that was used to plan a broader phase 2 reconnaissance to study damage in the Mississippi coastal area, New Orleans, and Southeast Texas (the area affected by Hurricane Rita). In the phase 2 reconnaissance, 26 experts from the private sector, universities, and federal agencies (including 6 from NIST) deployed during the weeks of October 10, 2005 and October 17, 2005. This report documents the observations made during these deployments and subsequent analysis of damage data and environmental actions. It also outlines the major findings of the NIST-led reconnaissance team. The report concludes with 23 recommendations for:
(1) improvements to practice that will have an immediate impact on the rebuilding of structures damaged or destroyed by the hurricanes;
(2) improvements to standards, codes, and practice; and (3) further study or research and development.
Keywords: Hurricane, wind, wind-borne debris, storm surge, surge-borne debris, flooding, major buildings, physical infrastructure, residential structures, building codes and standards, building practices.

Guide for Seismic Evaluation of Active Mechanical Equipment

The purpose of this Guide is to provide recommendations for evaluating the seismic operability of valves, pumps compressors, fans, air handling units, and chillers. The recommendations are in the form of seismic evaluation checklists, static and dynamic calculation methods and seismic testing protocols.
The Guide provides the background and technical basis for the proposed seismic evaluation methods. This background consists of equipment descriptions, analytical experience, seismic test experience, lessons learned from earthquake investigations, and observations of operating failure modes and equipment maintenance.
The Guide covers the seismic adequacy of the equipment itself, but does not address its power supplies, instrumentation and controls. These need to be addressed separately, if the equipment is required to operate during or after the earthquake.
Chapter 2 of the guide addresses the principles of seismic equipment engineering and provides a review of existing seismic qualification methods and standards.
Chapters 3 to 7 address the five classes of active mechanical equipment: Valves (Chapter 3), Pumps (Chapter 4), Compressors (Chapter 5), Fans and Air Handling Units (Chapter 6), and Chillers (Chapter 7).
Each one of these equipment chapters is structured in a consistent manner and addresses, in order: (1) equipment description, (2) equipment performance during earthquakes, (3) equipment performance in seismic tests, (4) methods, rules and limitations of seismic analysis, and (5) equipment vulnerabilities based on common – non-seismic – operation and failures (corrective maintenance). Each equipment chapter concludes with a seismic attributes checklist. In addition, the guide includes two chapters that apply to all classes of equipment: anchorage to concrete (Chapter 8) and evaluation of seismic interactions (Chapter 9). The seismic attributes checklist, together with the support and anchorage checks of Chapter 8 and the interaction checks of Chapter 9, constitute the basis for seismic qualification of the equipment.

Applications of Titanium Dioxide Photocatalysis to Construction Materials

Titanium dioxide photocatalysis is based on the semiconducting nature of its anatase crystal type. Construction materials with titanium photocatalyst show performances of air purification, self-cleaning, water purification, antibacterial action.

This book describes principles of titanium dioxide photocatalysis, its applications to cementitious and noncementitious materials, as well as an overview of standardization of testing methods.
