本文提出了一种分析斜拉桥的新方法,即用迭代法对由拉索支承的梁的位能进行迭代。发现迭代是收敛的,而且只需取傅立叶级数的前几项就足够了。尽管本文在求解数字例题中只用了线性分析的方法,但它也能考虑各种非线性因素的影响。在实用上,用线性解已是相当精确的了。本文提出的方法简单、迅速,且可用于电子计算机,甚至袖珍计算器。作者编制的电算程序能在几秒钟之内求解任何斜拉桥的问题。 This paper presents a new method for analyzing cable-stayed bridges by iteratively iterating the potential energy of the beam supported by the cable. It is found that the iteration is convergent, and it suffices to take the first few of the Fourier series. Although this article uses only linear analysis in solving numerical examples, it also considers the effects of various non-linearities. In practice, using linear solutions is fairly accurate. The method proposed in this paper is simple and rapid and can be used in electronic computers and even pocket calculators. The author’s computer program can solve any cable-stayed bridge problem in seconds.
