Аннотация: This paper proposes a method of reasonable selection of the fixation scheme, and the number of intermediates supports for straight multi-span beams in order to ensure the given values of the critical load from the compressive axial force. This axial force may be an external load or may occur, for example, as a result of a change in beam temperature. An effective way of providing the first critical force of the beam is to choose the appropriate method of fixing it: the type of the main supports and, if necessary, intermediate supports. This paper proposes a method of normalizing effective length factors, which enables to obtain convenient comparable values when choosing a fixation method and, as a result, to develop a method for a reasonable selection of a support arrangement system for a straight beam. The technique is based on the well-known theory of beam stability and uses effective length factors as a criterion for selecting the fixation scheme, which is formed after solving the corresponding differential equations of the beam state and is determined only by the fixing conditions. The obtained results can be used in calculations and design of any extended beam structures to control their stability by selecting the appropriate fixation scheme. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
