COUNTING FOR THE PROBABILISTIC NATURE OF GEOMETRIC IMPERFECTIONS FORM SPATIAL COATINGS ON THE STANDS BRACED-CANTILEVER TYPE
The article describes some types of monitoring the state of the geometry of the stationary frame-cantilever roof structure over the stadium with a capacity of up to 5 000 people. The results of monitoring the geometry of structures over the stands SC «Olympic» have been given. The methods take into account possible deviations of geometric in this type design, based on the finite element method in the variational formulation. We propose a method of accounting changes of design scheme of geometrically nonlinear operating stationary frame-cantilever structure covering over the stands at different stages of their manufacture, installation and operation.
