Abstract:The modeling methods,solution thoughts and features,which apply the embedded region and the non-nodal FEM in ABAQUS to simulate the reinforced concrete members,are introduced. The shortcoming of embedded region that it can’t restrict the rotation degree is expounded. The advantages and disadvantages of the embedded region and the non-nodal FEM are expounded through three examples. Meanwhile,it is indicated that the non-nodal FEM is advantageous in dealing with reinforced concrete members.
Keywords:finite element method  reinforced structure  building model  non-nodal connection  ABAQUS
