AbstractAbout AuthorsReferences
Peculiarities of the work of dowel connections on metal clamping plates in the roof structures of wood are considered. It is shown that a significant factor affecting the strength characteristics and consequently the durability of structures is the cyclicality of changes of temperature and humidity parameters in the environment of exploitation. Boundary problems of heat and substance mass transfer in the case of moisture condensation on a dowel and its diffusion into the layers of wood in the two-dimensional setting are formulated and solved. The results of problems solutions are illustrated by specific examples.
