摘要：
Methods for calculating the creep strain in the longitudinal bending of beams were considered by many authors (e.g., see [1]). The computations permit determining the deflection variation as a function of time and the critical time in which the beam compressed by the forces directed along its axis loses its stability. In the present paper, we consider the creep deformation of beams of various cross-section and show that the critical time can be increased by changing their structure.
