摘要
对国内外规范中关于振动舒适度的评价指标和相应限值进行较为系统的总结,并对其进行对比和评价。在现有的人行激励荷载特性和主要荷载模式的基础上,利用MIDAS/GEN软件对某一复杂长悬挑结构的长悬挑处廊道进行舒适度分析,利用国内外已有的频率、加速度评价指标对结构的舒适度进行评价,对类似结构的振动舒适度分析有一定的参考价值。
The paper reviews and compares some assessment criterias and corresponding limit value of vibration serviceablity in home and aboard standards.The vibration serviceablity analysis of a complex long-cantilevered structure under pedestrian load was performed by the author using the equivalent node load analysis method based on MIDAS/GEN.The analysis includes six loading cases.In the comparative study,frequency and acceleration limit assessment criterias,which are approved reasonable home and aboard,are adopted in this paper and some suggestions are made for the future vibration serviceablity study of similar structures.
