Abstract:Realistic Failure Process Analysis (RFPA~(3D)) software is used to
   simulate the short concrete-filled rectangular steel tube columns under
   axial compressive loading. The relationship between the ultimate bearing
   capacity and the length of the columns is presented, and the effect of
   cross-section area is also considered in the present simulations. The
   results of numerical simulation indicate that the ultimate bearing
   capacity is adversely affected by the length of the columns. As regards
   the ultimate bearing capacity, the simulation results agree well with
   the experiment observation. The results indicate that RFPA~(3D) seftware
   is effectively in capturing the failure characteristics of the
   concrste-fdied rectangular steel tube columns, denoting RFPA~(3D) could
   be used as numerical tool to evaluate the design of concrete-filled
   rectangular steel tube columns.
