This volume summarizes the authors' research at the Moscow's State Fire Academy. Uniquely practical, it shows how to predict the behavior in a fire of real building structures and includes data on the flammability of a range of wood varieties of differing age.

This volume describes fire behavior and fire protection of timbers in outdoors and indoors application mainly in construction industry. The Authors' novel approach considers the relationship between various species and age of timbers and its fire behavior at different thermal and fire loads. Quantitative data of ignition speed and flame propagation as well as generation of heat, smoke and toxic products are discussed. Analysis of fire resistance of various types of building materials based on timber of different species as well as the novel data on the effect of natural and accelerated aging of timbers on its fire behavior are discussed. The main practical methods of fire protection of new and ancient timber buildings and structures to increase its fire resistance are considered. The book should be useful for a wide range of readers: chemists, physicists, material scientists, architects, engineers, constructors and restorers.

Natural wood is considered as a natural composite material and it fire behavior and fire resistance depends simultaneously both on physical structure (morphology) and specificity of chemical structure of various wood species and age .The main experimental data on fire behavior and engineering recommendations on fire resistance of building constructions summarize the authors' results developed at State Fire Academy, Moscow, Russia Another unique point on the book is its practical content, one of the most important practical developments of authors' approach is ability to predict the behavior and longevity of real building structures and constructions at fire For the first time data has been presented on how the age of natural wood of various species (both very old and fresh wood) affects fire behavior The very novel industrial technology has been developed to considerably improve fire safety of building constructions based on natural wood using the intumescing (self-foaming) organic coatings which do not contain common fire retardant elements Wide range of readers and users: students, researchers, engineers, constructors, architects and restorers The book is divided on purpose in three parts and each group of readers can find useful information according to their specific interests In many aspects the proposed book can be characterized as a short but condensed encyclopedia on fire behavior and fire resistant of natural wood

This volume describes the modern data on fire behavior and fire protection of timber in outdoors and indoors application mainly in construction industry. The book discusses the most important topics of that area of science and engineering such as: Specificity of structure and properties of different timber species; Pyrolisis and oxidative decomposition of timber; The ignition of timber; Heat release characteristics and combustion heat of timber; Flame propagation on timber surface; Generation of smoke and toxic products at fire of timber surface; Generation of smoke and toxic products at fire of timber; Fire safety and fire resistance of timber building structures and constructions; Fire protection of timber building structures and constructions; Effect of natural aging of timber building structures on fire behavior and fire safety; The changes in fire behavior timber based on different of wood species after accelerated artificial aging.

The Authors' novel approach discovered the relationship between various species and age of timbers and its fire behavior at different thermal and fire loads. Quantitative data on ignition speed and flame propagation and generation of heat, smoke and toxic products are discussed for most types of timbers applicable in engineering practice. Analysis of fire resistance of various types of timber building materials and very new data on the effect of natural and accelerated aging of timber fire behavior are discussed. The main practical methods of fire protection of new and ancient timber structures using novel coatings (without regular fire retardants) are considered.

Most of the data contained in the book are based on the authors' research and practical experienceaccumulated during many years of their activity in the area. The book should be useful for a wide range of readers: chemists, physicists, material scientists, architects, engineers, constructors and restorers involved in study and practice of fire behavior and fire protection of timber.
