Streszczenie / Summary:

In the paper modelling and calculations of an asymmetrical bolted flange connection at the assembly
stage are presented. The physical model of the joint is based on a flexible flange element that
is connected with a rigid support by means of hybrid elements, which substitute bolts. Between the
flange element and the support, 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 preload distribution both during the bolted flange connection’s
assembly and after it has been completed. Results obtained from the calculations are compared with
experimental research described in
