Using ANSYS software to analyze the static performance of ridge-type LICS with large vector height,The influence of the structure span S, the height of the structure f, the number of the ring to the region and the number of radial nodes on the static performance of the structure are studied in detail. On this basis, the analysis of the natural vibration characteristics and seismic response of the structure are carried out, and the influence of the span and the height to the fundamental frequency of the structure is discussed. The research results show that: The static performance of ridge-type LICS with large vector height is good, The influence of the rise to the static performance of the structure is not much, The effect of the number of the ring and number of radial nodes to the static performance of the structure is complex.The Regularity of Structure natural frequency and vibration mode is strong, Structure base frequency is sensitive to span.The Seismic performance of structure is perfect, The maximum displacement of the structure after the earthquake is sensitive to he number of the ring.
