Preparation and finite element numerical simulation of glass fiber reinforced composite sandwich hollow columns

As a new type of architectural material and structure form, composite sandwich hollow column can be extensively used in all kinds of buildings and structures. This paper researches two different preparation methods of the columns, and studies the mechanical properties of the columns under axial compression by finite element numerical simulation. Results show that composite sandwich hollow columns under axial compression have three failure modes: strength failure, local buckling and overall buckling. Based on ANSYS, it can be concluded that increasing thickness of surfaces can improve load-carrying capacity of the column, and values of numerical simulation are very close to experimental or theoretical values.
