摘　　要：采用LANCZOS方法系统地分析了短程线型单层球壳的自振特性,考虑了不同矢跨比、不同跨度、不同屋面荷载、不同的杆件截面面积和不同支座条件等参数的影响,得出了短程线型单层球面网壳结构的自振规律。The free vibration characteristics of geodesic single-layer spherical reticulated shells are analyzed systernatieally with LANCZOS method. The influence of many kinds of parameters such as the ratio of rise to span, the span, the roof load, the size of grid and the condition of supports are concerned, and the rules of the free vibration characteristics of geodesic single-layer spherical reticulated shells are obtained.
