Optimal design of the elements of cross-domed systems
This article examines methods for reducing the thrust force (transverse forces) in the structural components of the cross-domed systems. Based on the analysis of several essentially different construction solutions in a spatial setting with the choice of the most optimal model. The space-planning decisions of the temple central part are considered. The particular attention is paid to the interior space of temple, namely the transition from full-squared cubing to round one. The structural components that perform this transition are considered. The symbolic meaning of the structural components of the Orthodox church is described. When calculating building structures, Lira's bundled software based on the finite element method was used. The three-dimension models of the cross-domed system were calculated. The Model № 1 consists of columns, girth arches with scoinsons, central drum and dome. The Model № 2 consists of columns, girth arches with trumpets, central drum and dome. The stress-strain state of 2 models was investigated under the application of loads. It was determined the most optimal model with the least thrust effort in the vertical structural components. Then the air links (tie-beams) are added to the calculated models and recalculation is carried out. In summary, a conclusion is made by the data obtained.
