A new type of pre-stress combinatorial frame structurew;15presented in this use of concrete composite board as the upper cord and the prestressed cable as the bottom chords. The de-tailed static analysis of the structure was made by the finite element analysis software of ANSYS. Research results showed that the closer the node vertical displacement to the center of the structure，the bigger the value was. Both the tensile stress and compressive stress appeared in composite board and web while the tensile stress in the cable and the bottom chords. The closer the rigging and pole for the bottom chords with the tensile stress to the center the bigger the value was. Both the displacement and extreme stress of the structure were higher than the requirement of the design and the regulation.
