| Abstract: | The development of the research on elastic-plastic ultimate loads of concrete-filled-steel-tube(CFST) is introduced. First, simple formulae were undertaken. Then, induction was used after a great deal of tests. Now, the finite element method is very popular. The methods of the elastic-plastic ultimate loads of CFST structures, such as beam-column under the axial compressions and arch rib, from only the geometric non-linearity accounted to the material non-linearity, from plane structure to space are presented. |
