摘要现代人行桥的特点是建筑要求轻、细、长的结构，这可能导致过度的振动问题。在过去的几十年里，有报道称发生了由混凝土引起的人行桥振动，特别是在日本的户田桥、伦敦的千禧桥和巴黎的索尔费里诺。1989年，我们在拥挤的人群通过时观察到户田桥的一种特殊的横向振动。数百名行人以同步的方式行走，这在结构中产生了显著的横向振动。大约10年后，当巴黎的索尔费里诺桥和伦敦的千禧桥在拥挤的人群通过时显示出类似的现象时，公众对桥梁引起的横向振动的关注显著增加。这三个最著名的案例引发了广泛的研究，并且由混凝土引起的振动已经成为振动研究中的一个重要课题。A consid.
AbstractModern footbridges are often characterized by architectural demands for light, slender, and long structures that may lead to excessive vibration problems. In past decades, occurrences of pedestrian-induced vibration on footbridges have been reported, notably at the Toda Bridge in Japan, the Millennium Bridge in London, and the Solferino in Paris. In 1989, we observed a peculiar type of lateral vibration at the Toda Bridge during the passing of congested crowds. Hundreds of pedestrians walked in a synchronized manner among themselves, which created remarkable lateral vibration in the structure. Approximately 10 years later, public attention on pedestrian-induced lateral vibration increased significantly when the Solferino Bridge in Paris and the Millennium Bridge in London showed a similar phenomenon during the passing of congested crowds. These three most well-known cases have triggered extensive study, and pedestrian-induced vibration has emerged as an important topic in vibration study. A consid...
