(四川理工學(xué)院建筑工程學(xué)院，自貢643000)[摘要] 分析了斜拉網(wǎng)殼這種典型雜交空間結(jié)構(gòu)的自振特性。通過改變網(wǎng)殼厚度、跨度、塔柱剛度和斜拉索剛度等參數(shù)，全面探討了該結(jié)構(gòu)的動力特性，得到一些有規(guī)律的結(jié)論，可為相關(guān)工程設(shè)計提供參考。

(School of Building Engineering, Si Chuan University of Science and Engineering, Zigong, 643000)Abstract: Free vibration properties for cable-stayed latticed shell, a land of typical hybrid space structure, are analyzed. By means of changing the thickness of latticed shells, the spans, the stiffness of tower columns and the stiffness of cables. the dynamic properties of the structure are totally discussed Some regular conclusions which can provide references for related structural design are presented.
Keywords: cable-stayed latticed shell; dynamic properties; parameter analysis
