（北京工業(yè)大學建筑工程學院 100022）[提要] 通過大量計算機分析，給出了在各種不同矢跨比、長跨比、厚跨比和波寬情況下，單層與雙層柱面網(wǎng)殼基本頻率數(shù)值表格與變化曲線圖，由此得出網(wǎng)殼基頻隨各參數(shù)的變化規(guī)律。設(shè)計人員可根據(jù)工程幾何參數(shù)直接由曲線圖表得到各網(wǎng)殼基頻，使用簡便、計算快速，可滿足工程精度要求。
[關(guān)鍵詞] 柱面網(wǎng)殼 基頻 設(shè)計圖表Based on large number of computer analyses,the variations of fundamental frequencies of both single-layer and doublelayer cylindrical lattice shells with various structural parameters are investigated, from which practical design charts of the fundamental frequencies are obtained. These charts are very simple to use. The designer can convenlently obtain the value of the fundamental frequency just in terms of basic structural parameters.
Keywords: cylindrical lattice shell; fundamental frequency; design charts
