| 摘 要： | 在简要介绍脉动风荷载的生成及拉索的多单元有限元模型的基础上,采用随机振动的动力时程法计算某斜拉网格结构的风振响应,并进行了参数分析。计算结果表明,与无拉索的网格结构相比,斜拉网格结构的脉动响应较小。在斜拉网格中考虑拉索本身风振与不考虑拉索本身风振,结构的风振响应差别较小。拉索的脉动响应主要与其所处的位置有关。 |
| 关 键 词： | 斜拉网格结构 脉动风 多单元 风振响应 |

| Abstract: | The random wind and multi-element model of the cable were introduced.The wind-excited vibration of the cable-stayed spatial latticed structure was analyzed by the method of dynamic time-history,and effects of parameters were discussed.The numerical results showed that the wind-excited response of the cable-stayed spatial latticed structure is smaller than that of the spatial latticed structure,and the wind-excited vibration of cables has a little influence on the structure.The response of the cable depends on its position. |
| Keywords: | cable-stayed spatial latticed structure random wind multi-element model wind-excited vibration |
