The article deals with the problem of lateral buckling of a wooden beam of rectangular cross-section, taking into account the initial imperfections under creep conditions. An algorithm for the numerical solution is presented. The linear Maxwell-Thompson equation is used as the creep law. The character of the growth of the deflection of the beam at various load levels is investigated and a new criterion is introduced to determine the critical time.
