The analytical model of the stress-strain state of a wooden compressed-bent rod at short-term loading by forces with unequal eccentricities and at presence of transverse loading is offered. In the calculation model the real diagrams of work of wood on compression and stretching are laid. The approximation of the curved compression chart takes into account the elastic-plastic properties of the wood. The method allows to solve the problem of determination of the limiting bearing capacity both by the criterion of buckling and by criteria of durability. The theoretical results are confirmed by experimental data and can be used for practical calculations of compressed-bent elements.
