【摘要】 本文根据目前人行荷载和舒适度评价的研究成果,模拟了不同工况下单人、多人有序和随机荷载,并对某大跨度钢结构连廊的振动特性和舒适度进行了分析。根据连廊结构的振动特性,借鉴相关研究,对大跨度钢结构连廊进行MTMD减振设计。结果表明,利用MTMD减振系统可以有效地控制结构的竖向振动,满足舒适度的要求。更多还原

【Abstract】 Based on existing researches about pedestrian load and comfort criterion,different pedestrian load models are developed to simulate activities of single person walking,regular or stochastic crowd walking. Vibration property and comfort of long-span steel corridor are studied.According to the vibration property,a MTMD system is designed in the corridor using the relevant achievements.It is shown that,the design of the MTMD system can control the vertical vibration of the corridor and meet the requirement of the comfort.更多还原
