| 摘 要： | 钢空腹夹层板由于结构高度小,适应跨度大,用钢量省,被广泛地应用于大跨度楼盖中.但由于结构自重轻、自振频率较小的特点,其更容易在人行激励作用下出现舒适度问题.本文首先对贵州都匀地区某新建酒店的大跨度钢空腹夹层板楼盖进行动力特性分析,分析其频率与振型,然后采用行走路线法对楼盖施加激励时程,进行舒适度时程分析.分析表明,按强度理论设计的钢空腹夹层板楼盖的自振频率较低,接近规范给定的限值.舒适度时程分析的加速度响应满足规范要求,可以用于工程实践.

| Abstract: | Steel vierendeel sandwich plate is widely used in large span floor system due to its characteristics of lightweight, thin, large span and saving steel. However, because of the characteristics of low natural fre- quency and thin floor, the problem of comfortableness will appear. The paper, first, does dynamic analysis of a large span special--shaped steel vierendeel sandwich plate of a hotel which was built in Guizhou province; second, does time history analysis of the finite element model. Analyses shows that the frequency of steel vi- erendeel sandwich plate which is designed by theory of strength is low and close to the specification limits val- ue. The acceleration response of the time history analysis meets the specification requirements; and this meth- od can be used in engineering practice. |
