摘要
振动舒适度问题是现代建筑结构中一个越来越值得被关注的问题.在考虑楼板安全性的基础上从人体舒适度的角度对楼板的设计方法进行了扩充.从影响楼板振动舒适度的若干因素如:楼板的厚度、长宽比、短边长度入手,以计权后的均方根加速度为评价指标,运用分析对比、数据拟合等方法,找出了满足振动舒适度要求的楼板的短边长度与楼板厚度的关系,并给出了简易计算公式.计算参数简便、计算结果与理论吻合程度高,可直接应用于工程设计实践中.
In modern structures, the more close concern is paid to the issue of vibration comfort degree. The traditional design method of building floor slab is based on the bearing capacity which is the most important factor for the safety. A new design method, not only considering the structure safety, but also concerning with the human comfort was discussed. A simple formula, which suits to calculate the minimum comfortable thickness of slab was derived from RMS acceleration method. This formula can be directly applied to engineering design due to its simple parameters and good coincidence of calculated result with theoretical results.
