Popis: |
Calculations of thin-walled concrete dome roofs of circular outline of different type under the influence of operational loadings with use of two modern program complexes are executed. Extent of influence on the intense state of strain (ISS) of dome covering of inclusion in team work of supporting ring from mass concrete and brickwork under different conditions of staying is evaluated. The analysis of features of forms of loss of stability of dome coverings together with supporting ring under different conditions of staying of dome on supporting ring is made It is investigated by the VAT of dome coverings as a part of construction from position of forecasting of possible forms of loss of stability. The technique of the solution of problem of optimization of such design with the choice of criterion and parameters of problem of optimization is constructed. use of opportunities of the Topological Optimization module of the final and element «MidasCivil» computer. Criterion function was considered dependent on thickness of dome, elastic modulus of Poisson’s ratio of material, arrow of raising of dome. |
