摘要

现代发展的柔性桥梁对荷载变化、瞬时变位、多种振型的动力问题,较静力更为敏感,增大了桥梁非线性问题的范围。本文从结构分析入手,通过讨论斜拉桥结构经典设计中遇到的难点,指出斜拉桥设计中主要的非线性结构问题,并将其分类,同时从静力和动力两方面给出斜拉桥非线性结构问题分析方法,并通过一些有代表性的实例来说明斜拉桥非线性结构问题。最后得到一些有意义的结论。

Abstract

Analysis on Non-linear Structure of Cable-Stayed Bridge Wang Jianping; Zhang Guanghui; Liu Lisheng(Lect., kept. of Engineering Mechanics, WUT,Wuhan 430070, China.) Nowadays, the development of cable supported bridges is concerned much more with the dymamic research on load variation, instantaneous position change and various vibration types than with the static problems, so as to broaden the range of research onnon-linear structure of bridge. This essay starts with the structure analysis, through the research on the difficulties in the course theclassical designs of cable-stayed bridges, points out the main non-linear structure problems included in the design and then, classifiesthese problems. Meanwhile, it offers the analysis methods on non-linear structure problems in the aspects of both dynamics and statics.Furthermore, it illustrates the non-linear structure problems of cable-stayed bridge by using some typical examples. As a result, somesignificant conclusions can be drawn from this essay. cable-stayed bridge, non-linear sturcture, non-linear analysis
