Download or read book Charring Rate of Selected Woods traverse to Grain written by Erwin L. Schaffer and published by . This book was released on 1967 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was designed to determine the charring rates for wood normal to the grain, and to evaluate the effect of fire intensity, species, specific gravity, moisture content, and annual ring orientation on these rates. Other material variables studied were the springwood to summerwood ratio and volatile extractive content. The effect of variation in moisture permeability, however, was not evaluated. Laminated wood slabs, 3 inches thick, of Douglas-fir, southern pine, and white oak were vertically exposed to fire on one surface. The rate of char development was constant when the specimens were exposed to uniformly increasing fire temperatures; charring rates at three constant fire exposure temperatures were described by a pseudo-first-order reaction equation with an Arrhenius temperature-dependent rate constant. Rates of char development in each species were related to the specific gravity and moisture content of the wood. The other material characteristics considered were directly related to specific gravity and moisture content or had no significant effect on the charring rate. (Author)

Download or read book Charring of Wood written by Esko Mikkola and published by . This book was released on 1990 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work describes a simplified model for charring of wood as well as experimental charring rate results for some wood species and wood products. The charring rate is affected by density and moisture content of wood, external heat flux and oxygen concentration of the surrounding air. The charring model can be used to calculate with ease and comparatively high accuracy relative changes in charring rate when any of the parameters describing the material or the surrounding conditions changes. This type of simple calculation method has not been presented earlier in the literature.

Download or read book Fire Hazard and Fire Resistance of Wooden Structures written by Sivenkov Andrey Borisovich and published by Springer Nature. This book was released on 2023-04-06 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph discusses fire hazard and fire resistance in wooden structures with a long duration of operation. Aside from its increasing importance for modern architecture, wood has been the most important building material in the past. It has a distinct aesthetic, high mechanical strength, and resistance against many environmental changes. These properties are evident in structures like the still standing Grinstead Chuch, which has been built in 1045. Readers will however learn about the decreasing fire resistance in wooden buildings with a long service live. Considering the cultural value of medieval wood buildings, this topic becomes increasingly relevant. The chapters discuss the mechanical, physico-chemical and thermophysical properties of wooden structures over different lifespans. Many factors contributing to the changing fire resistance in the ageing process of wooden structures, are explained. This book is a valuable resource for students, teachers and scientists in the areas of wood science, fire research and forestry.

Download or read book Wooden Fa ades and Fire Safety written by Linda Makovicka Osvaldova and published by Springer Nature. This book was released on 2020-07-17 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the results of an experiment assessing the impact of spruce wood joints on the creation and development of fire when these joints are applied within a façade. The book includes an extensive analysis of wooden cladding, which is a flammable material in which the elements are connected lengthwise using various types of joint. The parameters of the experiment, as well as the setting, material criteria and evaluation criteria are described in detail. The results confirm that the joint type used has an impact on the selected evaluation criteria and thus also on the potential spread of fire.

Download or read book Springer Handbook of Wood Science and Technology written by Peter Niemz and published by Springer Nature. This book was released on 2023-04-01 with total page 2064 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides an overview on wood science and technology of unparalleled comprehensiveness and international validity. It describes the fundamental wood biology, chemistry and physics, as well as structure-property relations of wood and wood-based materials. The different aspects and steps of wood processing are presented in detail from both a fundamental technological perspective and their realisation in industrial contexts. The discussed industrial processes extend beyond sawmilling and the manufacturing of adhesively bonded wood products to the processing of the various wood-based materials, including pulp and paper, natural fibre materials and aspects of bio-refinery. Core concepts of wood applications, quality and life cycle assessment of this important natural resource are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Structural Design for Fire Safety, 2nd edition Andrew H. Buchanan, University of Canterbury, New Zealand Anthony K. Abu, University of Canterbury, New Zealand A practical and informative guide to structural fire engineering This book presents a comprehensive overview of structural fire engineering. An update on the first edition, the book describes new developments in the past ten years, including advanced calculation methods and computer programs. Further additions include: calculation methods for membrane action in floor slabs exposed to fires; a chapter on composite steel-concrete construction; and case studies of structural collapses. The book begins with an introduction to fire safety in buildings, from fire growth and development to the devastating effects of severe fires on large building structures. Methods of calculating fire severity and fire resistance are then described in detail, together with both simple and advanced methods for assessing and designing for structural fire safety in buildings constructed from structural steel, reinforced concrete, or structural timber. Structural Design for Fire Safety, 2nd edition bridges the information gap between fire safety engineers, structural engineers and building officials, and it will be useful for many others including architects, code writers, building designers, and firefighters. Key features: • Updated references to current research, as well as new end-of-chapter questions and worked examples. •Authors experienced in teaching, researching, and applying structural fire engineering in real buildings. • A focus on basic principles rather than specific building code requirements, for an international audience. An essential guide for structural engineers who wish to improve their understanding of buildings exposed to severe fires and an ideal textbook for introductory or advanced courses in structural fire engineering.
