Calculation of the Rectangular Cross-Section Beams On the Side Buckling Taking into Account Creep

The article presents the derivation of the resolving equation for calculating the flat form of bending stability of the beams, taking into account creep. When deriving the basic equation, the application of the load with eccentricity, as well as the initial curvature of the beam is taken into account. The solution of the test problem for a wooden cantilever beam is presented. The value of the long-term critical load was introduced and it was shown that the load acting on the beam should not exceed it. A new criterion for determining the critical time is proposed. (paper)
