Desiring to build myself a wooden frame as unprofessional, I was looking for a practical and understandable book on the subject. This book is a quite what I wanted. It presents the basic principles of the structures as well as different methods of calculation to properly size the parts. This book addresses both roofs, floors and walls that the assemblies. I especially like the chapters on the strength of wood and static calculations that are very practical and understandable. In summary, a good book for a beginner who wants to start wood construction.
