| Abstract: | This paper deals with the common use of layout patterns and behaviors of the dot-pattern glaze cable-truss supporting system and advances the basic analysis method of the vibration characteristics. For the analysis of plane form cable-truss supporting system, ANSYS program was adopted to exam the influences of parameters of pre-stress, cross-sections and lengths of cables and bars to the vibration characteristic systematically. The relationships between each parameter and self-vibration frequency are obtained. These conclusions are of guiding significance for anti-wind and anti-earthquake design of this structure as well as the analysis of the anti-resonance of main and sub-main structures. |
