The Glued Laminated Wooden Arch

Westlam glue laminated wooden beams were introduced to Alberta, Saskatchewan and the Northwest Territories in 1987 with very encouraging results. Canada Mortgage and Housing Corp. approval had just been obtained and technical data and tables had been developed. Acceptance of Westlam in Ontario faced the problem of a total lack of familiarity with such a product. This report gives the steps taken to introduce the product, including obtaining acceptance by building authorities in Ontario and the western provinces, user acceptance, presentations to dealers, and technical support services.

Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.

The architect's favorite handbook-more informative and easier to use than ever! The Architect's Studio Companion is the laborsaving design resource that architects and builders have relied on for years. Now in its fourth edition, this industry standard continues its reputation as a reliable tool for the preliminary selecting, configuring, and sizing of the structural, mechanical, and egress systems of a building. Bestselling authors Edward Allen and Joseph Iano reduce complex engineering and building code information to simple approximations that enable the designer to lay out the fundamental systems of a building in a matter of minutes and get on with the design. Now in a flex binding that makes it even easier to use, The Architect's Studio Companion, Fourth Edition provides quick access to reliable rules of thumb that offer vital help for selecting, configuring, and sizing: * Structural systems * Heating, cooling, and electrical systems * Egress provisions, including exit stairways, parking garages, and parking lots * Daylight provisions The book concludes with precalculated tables of building code height and area limitations.

Prepared by the Subcommittee on Evaluation, Maintenance, and Upgrading of Timber Structures of the Committee on Wood of the Structural Division of ASCE. This report presents information on technical aspects of inspection, evaluation, reinforcement, repair, and rehabilitation of timber structures. Any structure, regardless of the material from which it is made, may be subject to a review of its ability to perform a specific function or functions. This report reviews factors that influence the serviceability of wood structures, including loadings, duration of loads, temperature, moisture and weathering. Effects of chemicals and fire, as well as insects, fungi, and other organisms that attack wood are also covered. Designing to avoid problems caused by these factors is discussed. Inspection techniques and equipment are described, along with guidelines on where to look and what to look for. A section of evaluation of wood structures includes criteria such as structural analysis, determination of loads, and estimating load carrying capacity.
