Paperback. Condizione: New. Print on Demand. This book presents a set of new basic grading rules and working stresses for softwood and hardwood structural timbers, with the purpose of introducing greater efficiency in the use of timber in construction. The book is the result of many years of research by the Forest Service and addresses the current lack of standardized grading rules within the construction industry. Before the development of the rules presented in this book, working stress limits were assigned to individual species without accounting for differences in material quality, making this book the first of its kind. The author provides a detailed explanation of the rules and stresses, which are based on the results of hundreds of thousands of tests of small clear specimens, as well as numerous tests on structural timbers containing defects. They also account for differences in the strength and character of various species, ensuring safe working stresses. This book is an essential read for anyone involved in structural timber use, including manufacturers, consumers, and builders. By providing clear and concise rules and stresses for structural timbers, this book will aid in the more efficient use of available material, ultimately contributing to the safety and longevity of timber construction.
