摘要:
大跨度人行悬索桥具有轻柔、低阻尼、基频小等特点决定了其对人行荷载激励较为敏感。以一钢箱梁自锚式人行悬索桥设计方案为背景,基于ABAQUS有限元平台,以国际桥梁及结构工程协会(IABSE)建议的单人步行激励为基础研究了人行悬索天桥的振动特性。结果表明:此类桥梁一阶频率位于2 Hz左右,接近于人行步频,易产生桥面共振,降低桥梁的使用舒适性及安全性。针对这种现象提出了采用调谐质量阻尼器(MTMD)进行调节,最大减振率达到45.1%,各工况下平均减振率可达37.7%。
Abstract:
Long-span pedestrian suspension bridges had notable characteristics of light weight and low nature frequency,thus it was more sensitive to excessive vibrations.A steel box girder self-anchored suspension design was used,and the vibration response to the walking of the people on the pedestrian suspension bridge was analyzed based on ABAQUS finite element platform. Results showed that the first order frequency of such bridge was about 2 Hz.The value was close to pedestrian loading frequency,thus reducing the comfort feature and safety.The tuned mass damper(MTMD)was utilized to solve the problem.The maximum attenuation rate under various working conditions was up to 45.1% and the average attenuation rate was 37.7%.
