Abstract. Determination of the values of the critical forces causing the loss of stability of centrally compressed wooden beams in the composition of building structures is a necessary requirement when checking their bearing capacity. For this reason, it is necessary to develop a scientifically grounded design model for determining the coefficients of the design lengths of centrally compressed wooden elements associated with often installed elastic supports or with an elastic foundation. The article provides a solution to the problem of their stability with various methods of supporting the ends of the beam (pivotally fixed ends; one of the ends is pinched, the second is fixed pivotally; both ends are pinched; one of the ends is free, the second is pinched). The results obtained in the form of graphs of changes in the coefficients of the calculated lengths of compressed wooden beams associated with an elastic base are recommended to use for assessing their stability under central compression. The results of the solution presented in the article can be used to determine the buckling coefficients of compressed wooden beams associated with an elastic foundation.
