Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.

Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the tree. The wood then begins to lose most of its moisture by drying, resulting in changes in most of its physical properties. These changes, and their relationship to the environment to which the wood is subsequently ex posed, are the subject of this book. The text consists of six chapters. The first chapter discusses cer tain empirical relationships between wood and water, methods of measuring wood moisture content, factors which affect its equilib rium moisture content, and the effect of moisture content on wood strength. The second chapter treats the thermodynamics of moisture sorption by wood, inc1uding enthalpy, entropy, and free energy changes. The third chapter discusses some of the theories which have been proposed to explain the sorption isotherms for hygroscopic ma terials such as wood. Chapter 4 considers hygroexpansion or the shrinking and swelling of wood associated with moisture change. Chapter 5 is concerned with how moisture moves through the cell wall of wood in response to both moisture and temperature gradients. The sixth and final chapter discusses the theoretical and practical aspects of the electrical resistance and dielectric properties of wood, in c1uding the principles involved in their application in electrical moisture meters.

A simple, practical, and concise guide to timber design To fully understand structural design in wood, it is not sufficient to consider the individual components in isolation. Structural Wood Design: A Practice-Oriented Approach Using the ASD Method offers an integrative approach to structural wood design that considers the design of the individual wood members in the context of the complete wood structure so that all of the structural components and connectors work together in providing strength. Holistic, practical, and code-based, this text provides the reader with knowledge of all the essentials of structural wood design: Wood structural elements and systems that occur in wood structures Structural loads—dead, live, snow, wind, and seismic—and how to calculate loads acting on typical wood structures Glued-laminated lumber and allowable stresses for sawn lumber and Glulam The design and analysis of joists and girders Floor vibrations The design of wood members subjected to axial and bending loads Roof and floor sheathing and horizontal diaphrams Exterior wall sheathing and wood shear walls The design of connections and how to use the connection capacity tables in the NDS code Several easy-to-use design aids for the preliminary sizing of joists, studs, and columns In keeping with its hallmark holistic and practice-oriented approach, the book culminates in a complete building design case study that brings all the elements together in a total building system design. Conforming throughout to the 2005 National Design Specification (NDS) for Wood, Structural Wood Design will prepare students for applying the fundamentals of structural wood design to typical projects, and will serve as a handy resource for practicing engineers, architects, and builders in their everyday work.
