Book Description
The objective of this study is to develop a protocol for evaluating and responding to potential strength-reducing characteristics that develop in lumber from stands following a regional catastrophic event. This new protocol is intended to be distinct from the standardized lumber testing programs that are in place to support the development of structural design values. Under this two-year project, a general protocol has been drafted and a limited pilot study was undertaken to demonstrate its efficacy by using shake in post mountain pine beetle (MPB)-killed lodgepole pine lumber as an example. This protocol provides guidance on the identification of suitable characteristics for study, the design of an exploratory survey for assessing frequency of appearance, the approach for collecting samples for strength testing, the analysis of the test results, and, if necessary, the development of supplementary grading rules to respond to possible impacts to the lumber strength from these characteristics.--Document.

Book Description
The general objective of this study was to supplement through data analysis the development of a quality assessment protocol for post-mountain pine beetle (MPB) wood that is consistent with standard North American procedures for testing and evaluating commercial structural lumber. The specific data analysis objectives were to determine the usefulness and limitations of existing data collected in past pan-Canadian cross sectional studies and how they may be used to assist in developing regional longitudinal programs. The second objective was to extract existing data on MPB-relevant characteristics from industry databases relevant to their frequency, and severity relative to grade rules. The techniques developed in this analysis are expected to form part of the evaluation framework of the quality assessment protocol.--Document.

Book Description
The Rapid Visual Screening (RVS) handbook can be used by trained personnel to identify, inventory, and screen buildings that are potentially seismically vulnerable. The RVS procedure comprises a method and several forms that help users to quickly identify, inventory, and score buildings according to their risk of collapse if hit by major earthquakes. The RVS handbook describes how to identify the structural type and key weakness characteristics, how to complete the screening forms, and how to manage a successful RVS program.

Book Description
Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 18. Landslides are a constant in shaping our landscape. Whether by large episodic, or smaller chronic, mass movements, our mountains, hills, valleys, rivers, and streams bear evidence of change from landslides. Combined with anthropogenic factors, especially the development and settlement of unstable terrain, landslides (as natural processes) have become natural disasters. This book charts our understanding of landslide processes, prediction methods, and related land use issues. How and where do landslides initiate? What are the human and economic consequences? What hazard assessment and prediction methods are available, and how well do they work? How does land use, from timber harvesting and road building to urban and industrial development, affect landslide distribution in time and space? And what is the effect of land use and climate change on landslides? This book responds to such questions with: • Synopses of how various land uses and management activities influence landslide behavior • Analyses of earth surface processes that affect landslide frequency and extent • Examples of prediction techniques and methods of landslide hazard assessment, including scales of application • Discussion of landslide types and related costs and damages Those who study landslides, and those who deal with landslides, from onset to after-effects—including researchers, engineers, land managers, educators, students, and policy makers—will find this work a benchmark reference, now and for years to come.

Book Description
Extreme weather and climate events, interacting with exposed and vulnerable human and natural systems, can lead to disasters. This Special Report explores the social as well as physical dimensions of weather- and climate-related disasters, considering opportunities for managing risks at local to international scales. SREX was approved and accepted by the Intergovernmental Panel on Climate Change (IPCC) on 18 November 2011 in Kampala, Uganda.

Book Description
This manual provides guidance on evaluating the condition of the concrete in a structure, relating the condition of the concrete to the underlying cause or causes of that condition, selecting an appropriate repair material and method for any deficiency found, and using the selected materials and methods to repair or rehabilitate the structure. Guidance is also included on maintenance of concrete and on preparation of concrete investigation reports for repair and rehabilitation projects. Considerations for certain specialized types of rehabilitation projects are also given.

Book Description
Updated in its 3rd edition, Basic Methods of Policy Analysis and Planning presents quickly applied methods for analyzing and resolving planning and policy issues at state, regional, and urban levels. Divided into two parts, Methods which presents quick methods in nine chapters and is organized around the steps in the policy analysis process, and Cases which presents seven policy cases, ranging in degree of complexity, the text provides readers with the resources they need for effective policy planning and analysis. Quantitative and qualitative methods are systematically combined to address policy dilemmas and urban planning problems. Readers and analysts utilizing this text gain comprehensive skills and background needed to impact public policy.
