【 摘 要 】

With the progress of technology and the constant improvement of the requirement for the quality of life, people tend to choose light and long-span structure. Due to damping of the long-span floor is small, the fundamental frequency is low, which will produce vertical vibration which exceed a certain limit will affects the security of buildings under the action of pedestrian vibration. Firstly, the large-span floor vertical vibration comfort control standards and design methods were introduced in this paper. Next, the research status of walking load model was summarized. Then, the critical calculation methods of the vibration response were summed up. Finally, the existing problems of comfort control standards, design methods, walking load model and the floor response analysis were discussed and possible research directions were also pointed out.
