- Abstract:
- In order to investigate the influence of the lateral resistance by the core tube on buckling mode and critical buckling load, the simplified mechanical model of the steelconcrete mixed structure system was established. Based on the finite element analysis, the influence of the relative relations of the frame and tube for steelconcrete mixed structure system on buckling mode were studied. According to the different buckling modes, the steelconcrete mixed structure system was categorized into four types, and the reliable judgment standard of buckling mode was summarized. Furthermore, the simplified algorithms of critical load corresponding to various buckling modes were put forward. The study results show that the calculation results of the simplified algorithm are accurate and reliable, can provide references for the designer.
