（浙江大學(xué)土木系 杭州 310027）[提要] 在簡述斜拉網(wǎng)架的構(gòu)成原理及其工程應(yīng)用的基礎(chǔ)上，根據(jù)考慮幾何非線性影響的斜拉網(wǎng)架分析程序，通過模型試驗(yàn)和大量算例對此類結(jié)構(gòu)的計(jì)算模型和結(jié)構(gòu)在不同布索形式、不同塔柱形式、不同斜拉索剛度和不同塔柱剛度等情況下的靜力特性進(jìn)行了分析研究。文中還介紹了浙江大學(xué)司令臺斜拉網(wǎng)架的設(shè)計(jì)與施工。并提出了一些可供工程設(shè)計(jì)參考的意見。
[關(guān)鍵詞] 斜拉結(jié)構(gòu) 網(wǎng)架結(jié)構(gòu)特性 雜交結(jié)構(gòu) 幾何非線性In this paper, the principles of constitution and the engineering application of the cable-stayed space grids are described, a model test is made. By a lot of examples calculated with the program of non-linear analvsis of cable-stayed space grids, the calculated model and the-static structural behavior of this sfructural system with different arrangement of cables, different shape and stiffness of the tower, different stiffness of the cables are studied.
This paper also introduces the design and construction of the cable-stayed space grids con-structed at the sports ground of Zhejiang University, and some reference opinions on engineering design are recommended.
Keywords: cable-stayed space grids; structural characteristics; hybrid structure
