Study on Stability Behavior of Cable-Stayed Ultra-High Strength Steel Column with Welded I-Section

Overall elastic-plastic stability behavior of cable-stayed ultra-high strength steel (660MPa) column with welded I-section is studied by geometric and material nonlinear FEM of software ANSYS. Longitudinal residual stresses and initial imperfections are taken into consideration. The results indicate...

Zusammenfassung:Overall elastic-plastic stability behavior of cable-stayed ultra-high strength steel (660MPa) column with welded I-section is studied by geometric and material nonlinear FEM of software ANSYS. Longitudinal residual stresses and initial imperfections are taken into consideration. The results indicate that cable-stayed type can significantly improve overall stability bearing capacity and effectively control mid-span deflection of ultra-high strength steel column.
