| 摘 要： | 研究结构的动力特性对结构的分析具有重要作用。文章通过有限元分析软件对一系列含有加强层的高层框筒结构模型进行了模态分析,得到了结构的基本周期,并描述了结构的前10阶振型图的振动规律;通过对比可明显看出:加强层的设置使得结构周期变短,刚度增大;且随加强层设置数量增多,周期呈现减小走势,结构刚度呈增大趋势,这充分说明在合适的位置设置加强层能很好的改变结构的刚度。

| Abstract: | Researching structural dynamic characteristics plays an important role to the structure analysis. The author utilizes finite element program to carry out modal analysis of a series of high- rise frame- tube structures with horizontal strengthened storey and get the basic period of structures, and describes the vibration rules of the top 10 bands of mode shape of the structures. By comparing the above data and drawing the following conclusions: first, setting strengthened layer makes the structure period bec... |
