In this paper, the behavior of concrete-filled double skin steel tubes (CFDST) with simply supported boundary condition was analyzed by Finite Element Analysis method. The Finite Element analysis mode was established and the results have a good consistent with experimental results. The work mechanic and full range analysis of concrete filled double steel tube under lateral impact were analyzed, the results show that the damage of CFDST with simply supported boundary condition under lateral impact is in ductile manner.

To realize axial load behavior of CFDST, ANSYS is used to analyze the process from load to destruction that hollow section ratio is the main variable parameter. To explore the validity of finite element analysis software, axial compressive strength is calculated combined with formulas of existing criterions. The results show the finite element results have a good agreement with text values and calculation.

Fixed Boundary Condition

As a new type of steel-concrete composite structure, Concrete-Filled Double Skin Steel Tubes not only have the advantages of the traditional steel concrete structures, but also carried out cross-section and great bending stiffness. This structure is widely used in high-rise buildings, bridges and power facilities. During the whole life cycle, concrete-filled double skin steel tubes may inevitably suffer from various impact loads. In current the research about steel-concrete composite structure focuses on the performance about axial compression, bias, bending, and low cyclic loads. but the research about it under lateral impact is equally import. In this paper, the behavior of concrete-filled double skin steel tubes (CFDST) with fixed boundary condition was analyzed by Finite Element Analysis method ,to analyze the destruction modal, impact force (F) , deflection () as well as other dynamic responses of CFDST under different lateral impact energy. The work mechanic and full range analysis of concrete filled double steel tube under lateral impact were analyzed. The results show that the damage of CFDST with fixed boundary condition under lateral impact is in ductile manner. Analyzed the whole process of the dynamic response basically , laid the foundation for further parametric analysis and practical calculation method.
