Tsarynnyk O. Limit Load, Strength and Deformation of Reinforced Concrete Folded Domes

Reinforced concrete domes assembled from pre-cast folds with dry joints. The purpose of the study was to determine their bearing capacity, collapse mode and mode of deformation. The research was conducted by experimental (with a 1:10 scale model and its fragments) and theoretical (based on limit load analysis) methods using electrical tensometers and automatic deformation measurers, deflectometers, microindicators, computer software Microsoft Office'97 and AutoCAD LT 97. An equations were developed for determining a bearing capacity and quantitative parameters of collapse mode for reinforced concrete folded domes. Their analysis, design and optimization proposals were worked out. The limit load analysis was applied for the new type of spatial structures and experimentally established was a bearing capacity and collapse mode of such domes. Developed approach could be used in analysis and design of long span roofs for industrial and civil buildings.
