Modeling the Construction Stages of Large Span Spatial Unique Buildings of Complex Geometry

Abstract

The results of experimental-theoretical studies of precast-monolithic reinforced concrete shells of complex geometry, assembled from enlarged elements at the assembly stage, are presented. The studies were carried out on full-scale composite shells 116 m, 96x88, 48x48 m and 18x36 m, its enlarged elements 3x18 m and 3x24 m, as well as on a shell model at a scale of 1:15, 1:10 and 1:4. The stress-strain state of composite shells was investigated for different versions of mounting and uncoiling. Recommendations are given on rational methods of erection and incineration of shells from enlarged elements for public buildings.
