Buckling analysis of a complex high building with hybrid structure

The building was carried buckling analysis integrally and partially.Finite element method was applied to analyze the overall buckling with SAP2000 program.Considering the boundary constraints of surrounding components,software ANSYS was used on a single column for buckling analysis,studying the effects of wind-resisting trusses on the stability of the columns supported by them.Results showed that the wind-resisting trusses changed the buckling modes of the columns supported by them and improved their maximum buckling loads.Load distribution had a certain influence on the maximum buckling loads of the structure.Reliable result could also be obtained by partial buckling analysis with proper boundary conditions.
