Strand-based engineered wood products (EWPs) have been widely employed in construction since their emergence in the 1970s. The use of strand-based EWPs can significantly increase the yield of forest resources by utilizing submarginal logs and branches. In this chapter, the strand-based EWPs, including oriented strand board (OSB), laminated strand lumber (LSL), and oriented strand lumber (OSL), are discussed in terms of their fabrication, properties, and uses in construction. Specifically, the manufacturing requirements for elements (i.e., strands), such as dimension, density, and moisture content, are introduced. The major manufacturing processes, such as selection of adhesives, pressing parameters, and thickness control, are also discussed. In addition, the engineering properties and uses of these EWPs are illustrated. Furthermore, some innovative applications of these products such as hybrid cross-laminated timber are presented in this chapter.

This paper presents the development of a visual inspection methodology for engineered wood products that are commonly used in residential construction in the USA. Engineered wood products include wood composite structural elements such as I-joists, oriented strand board, and structural composite lumber products, and metal plate connected wood trusses. Due to the proprietary nature of wood composite engineered products, there are no uniform standards between different manufacturers for installation and use. If improper installation methods are used, engineered wood products may not be able to safely carry design loads. Improper use or modifications constitute prescriptive code violations. Construction errors that result from the unique installation requirements demonstrate the need for specific inspection methods to detect installation errors early in the construction process. The goal of this research is to develop an expert-validated visual inspection methodology, associated knowledge base, and software application for selected engineered wood products and hanger hardware for non-compliance at the pre-drywall stage of new residential construction. A modified Delphi method was used to solicit and refine inspection methods from subject matter experts. Based on these results, an inspection method and computer software application were developed. The method establishes a systematic expert-validated inspection procedure that identifies known high-risk areas for installation problems for engineered wood products. The software contains the instructions for implementing the inspection method, a reference library of authoritative installation guidelines and illustrations, the ability to document observed defects, and a vehicle to create a report. The experts validated the method and software application, and confirmed the usefulness for detecting construction errors.

Ultrasonic Techniques

The use of ultrasonic techniques to evaluate the properties of engineered wood-based materials is discussed with respect to research to date and the use of more advanced techniques. The latter is critical because of the rapid evolution from solid wood to reconstituted structural materials. In addition, although considerable research has been done, there have been few introductions into manufacturing. This chapter traces the history of the use and latest developments of ultrasonics in several key areas, particularly the measurement of adhesive curing and quality in composites and laminates, and detection of flaws in solid wood materials. The techniques reviewed apply to product development, material properties, process control, product quality assessment, and evaluation of products in service.

Quaking aspen (Populus tremuloides Michx.) is a remarkable species that performs several significant ecological roles throughout its range while at the same time is facing ever-increasing harvesting pressure. Although its full product potential remains untapped, aspen utilization has increased noticeably in the past 15 years as it has become a desired species for engineered wood products such as oriented strand board, and a preferred hardwood in the production of high quality pulp and paper products. Concurrent with this increase in aspen utilization has been an increase in the importance of ecological concepts in forest management. Any new silvicultural concepts in aspen management designed to address these ecological concepts must be grounded in the silvics and life history traits of the species. Here we present three trends in aspen management; aspen retention, a renewed interest in aspen thinning, and the advent of cut-to-length (CTL) harvesters that allow forest managers to address these considerations by capitalizing on aspen's unique characteristics. Finally, we discuss traditional harvesting methods and these trends in the context of their genetic implications. Key words: aspen management, retention, thinning, cut-to-length harvesting, genetic variation, genetic diversity

The sustainable building design movement has gained momentum within the United States in recent years. This has led to a proliferation of green building certification programs like Leadership in Energy and Environmental Design (LEED) and the development of engineered wood products (EWP) like cross laminated timber (CLT). Often, architects serve as the conduit between green building construction material and their use in construction. There is need to investigate the perceptions and practices of architects on the topic of green building certification and EWPs. In partnership with the American Institute of Architects (AIA), this study surveyed registered architects practicing in Arkansas to a) examine interest in and application of LEED certification and b) beliefs related to sustainability, affordability, and availability of EWPs. Results suggest a majority of architects surveyed have interest in the LEED program and have previously earned LEED-certification for a building design. Respondents rated the importance of improving human health and well-being as especially high but appear to doubt the ability of EWP to contribute to sustainable design. Analysis revealed that CLT use is significantly lower than that of more typical EWPs such as plywood panels and glue laminated timber. Architects also indicated that the affordability and availability of modern EWP represent significant barriers to their utilization within the state. To increase the rate of sustainable development, it will be necessary to highlight benefits to human and environmental health and generate interest amongst architectural clientele.
