Abstract:
Using the program ANSYS, finite element model of the rung-shape long-span tensile cable-membrane structure in Foshan Century Lotus Stadium was conducted to investigate its dynamic characteristics and its mechanical performance under seismic loading. Study results indicate that the natural frequencies of the structure are all lower and frequency spectrums concentrate in a small range, and the frequency jumping phenomenon isn't in evidence. The structure's vibration is mainly vertical vibration, and its lateral stiffness and torsion rigidity are well. To ensure that the modal mass participating coefficient is more than 90%, the contributions of the former 140 modes should be considered when the analysis of response spectrum is done. Because the seismic loading can greatly influence the internal force of the upper compression ring, the lower compression ring, and the truss web, it should be calculated in the load combination. When the seismic loading on the structure is from different directions, the internal force and displacement of the structure have significant difference. So the effects of the different directions of the waves and their combinations should be considered together.
