Research on crack principle and reinforcement method of wood structure

Abstract

wood structure material is an ancient building material, which has played an important role in the development history of
human architectural culture and showed its unique charm. Wood structure building materials still occupy an important position in modern
architecture because of their light weight and high activity. At the same time, with the development of modern green architecture, wood
structure building materials will re emit light. For wood structural materials, because of its high activity, it will expand and shrink with
the change of environment. At the same time, its internal fi ber structure will also change with the change of time, so cracks will occur.
Cracks have a serious impact on the service life of wood structure buildings. Targeted reinforcement measures should be taken according
to the types of components, causes of cracks, crack width, crack depth, crack hazards and other factors. This paper analyzes the causes and
classifi cation of wood structure cracks, and discusses the reinforcement methods of wood structure cracks, hoping to provide some eff ective
ideas for the research and practice of wood structure reinforcement.
