Design features of bolted connections of structural elements of two-layer metal domes resulting from errors of their fabrication and assembly

Abstract

The paper describes the dependence of errors occurring in the frames of two-layer metal domes as a result of inaccuracy of actual geometric dimensions of assembly elements. The effect of errors on bolted connections of the individual members in the joints of the frame is demonstrated. The evaluation of the influence of errors on assemblage process and associated adjustment operations is given. Sequence of operations for different methods of assembly of the frameworks of metal domes are described. The results of statistical investigations of the probable clearances in the joints are presented.
