Steel pedestrian bridges have advantages such as lightweight and easy construction. However, the problem of human-induced vibrations has always been an important issue that needs to be solved in design and use. This article systematically analyzes and explores the research on the comfort and control of human-induced vibrations in steel pedestrian bridges. Firstly, the basic concepts and classifications of steel pedestrian bridges are introduced, and the mechanism and influencing factors of human-induced vibrations are analyzed. The existing control methods and research progress are discussed, and future research directions and focus are proposed.Keywords: steel pedestrian bridge; human-induced vibration; comfort; control research一、讨论背景人行桥是城市中不可或缺的重要组成部分,它能够连接两个不同高度的区域,为人们提供便利和安全的通行。钢结构人行桥由于具有轻量化、施工方便等优点,近年来得到了广泛应用。然而,由于人行桥本身的特别性质以及行人步行的不规律性,钢结构人行桥在使用过程中容易发生人致振动问题,给行人的舒适度和安全性带来一定的影响。人致振动问题不仅仅存在于人行桥上,在其他领域也有广泛的应用。因此,人致振动问题的讨论对于提高行人舒适度、保障行人安全具有重要意义。二、讨论内容和方法本文主要针对钢结构人行桥人致振动舒适度及其控制讨论进行系统分析和探讨。讨论内容主要包括以下几个方面:1. 钢结构人行桥的基本概念和分类;2....
