Abstract

[A complex stress–strain state (compression with blending) usually occurs in parts of spacer building structures (arches, frames), with out-of-site loading of rod systems (upper truss belts), columns, etc. Studying of reinforces wooden structures and research of stress–strain state under short-term and long-term loads required developing calculation methods for such constructs and taking into account properties as stress–strain structures’ state, heterogeneity of materials in complex structure, work compatibility, creep of wood and glue, etc. Assumption of perfect material elasticity is often applied when calculating building structures. The idea of perfect material elasticity (the basis of classical theory of elasticity and structural mechanics) for many materials is sufficiently confirmed by experiments with short-term loading at low-stress level. At the same time, with long-term load even at relatively low level of stress, some materials including wood reveal deformability at constant stress, i.e., they have creep. In this regard, accounting for creep in reinforced wooden elements is an integral part of structural calculations for beautiful states. ]
