Behaviors of Polyurethane Filled Double Skin Steel Tubular Members

Abstract:

Based on the nonlinear finite element software, the mechanical properties of polyurethane filled double skin steel tubular (PFDSST) members with different hoop coefficients and slenderness ratios under axial compression have been studied by nonlinear finite element software. On the basis of the researches on the numerical simulation results, it was summarized that the influences on stability, ductility and properties of the PFDSST members under axial compression, and then the work processes of the PFDSST members have been revealed deeply, the theoretical basis for the designs of the PFDSST members was established.
