【摘要】 大跨度空间结构楼盖的人行舒适度问题是结构设计中不可忽视的重要因素。在对结构舒适度使用性能的评价方法和评价标准总结归纳的基础上,提出了通过分析楼盖结构的振动特性,如最小自振频率、振动峰值加速度等,来控制楼盖结构的刚度,作为结构舒适度设计依据的方法。设计方法成功应用于财富中心的大跨度悬吊楼盖结构设计,并结合回廊第1阶的自振频率及模态的工程实测结果,验证了分析方法的可靠性。更多还原

【Abstract】 The vibration comfort design of large-span floor is an important issue of structure design.Based on the summarization of evaluation method and criterion of vibration comfort performance,the vibration comfort design method of adjusting the stiffness of floor through analyzing its vibration behavior was proposed.The method was successfully used in the structure design of the suspended floor of Prosper Center,and it was also proved to be reliable through experiment.更多还原
