The Analysis of the Elastoplastic Carrying Capacity of Solar Dome with Geometric Imperfections
Abstract: Eigenvalue buckling analysis of solar dome was done firstly, then the the buckling modes were got and the most unfavorable mode was pointed. The influence factors of bearing capacity, such as the form and bigness of geometric defect, were discussed. The influence of prestress and the section of rod was further studied. The result shows: The second-order buckling mode is the most unfavorable mode; as the prestress of rop grows, the influence of geometric defect to elastoplastic carrying capacity increases firstly and then decreases; as the section of rod changes, the influence of geometric defect to elastoplastic carrying capacity essentially unchanged.
