| 摘 要： | 通过有限元ANSYS软件模拟,在大跨度网壳结构中增加含有螺栓的平板橡胶支座.分别对含有6种不同水平刚度的平板橡胶支座的网壳结构进行分析,得到平板橡胶支座应用在大跨度结构中的动力响应.结果显示:水平刚度的增加有利于跨中挠度的减小,但杆件内力变化呈先增大后减小的趋势.

| Abstract: | The finite element software ANSYS was used to simulate the large-span networked shell structure with bolted planar rubber supporting seat,which had six different horizontal stiffness.The dynamic response of the shell structure with such rubber seat was analyzed.Its result showed that the increase of the horizontal stiffness of the rubber seat would be beneficial to the decrease of the middle-span deflection,and the variation of inner force of the rod exhibited the trend that the inner force increased at fir... |
