摘要：
Prestressed stayed columns with two crossarms are investigated for stability and maximal loading capacity. First, analytical geometrical derivation of minimal and maximal critical loading under optimal prestressing is presented. Second, geometrically nonlinear analysis with imperfections (GNIA) using ANSYS software is employed to receive numerical values of critical and maximal loading of "nearly perfect", ideal column. Finally, imperfect column with large initial deflections corresponding to Eurocode demand is investigated for various prestressings. In the conclusion, the comparison of analytical and numerical values is provided and comparison of the same specific column with either one or two crossarms is evaluated.
