摘要：
The article deals with modelling and calculations of asymmetrical multi-bolted connections at the assembly stage. The physical model of the joint is based on a flexible flange element that is connected with a rigid support by means of the spider bolt models. Between the joined elements the nonlinear Winkler model of a contact layer is taken into consideration. A computational model of the system is proposed, which makes it possible to analyze how the tightening sequence affects the distribution of preload both during the multi-bolted connection assembly and after it has been completed. The sample results obtained from the calculations are presented.
