| 摘 要： | 通过对日立电梯试验塔风洞试验结果的分析,表明试验塔原设计方案容易引起结构横风向共振,结构横风向的最大基底剪力以及基底弯矩的响应值可以达到顺风向的3倍左右。在结构设计中通过对建筑外形以及结构动力特性等方面的调整,使结构横风向的最大基底剪力以及基底弯矩的响应值减小至与顺风向基本相当,并在实际工程设计中予以采用。表明横风向作用在该类结构抗风设计中的起着不可忽视的作用,并针对这一特点提出了在结构设计中可以应用的加强措施。 |

| Abstract: | The wind tunnel test result of Hitachi-Elevator-Tower was analyzed in the paper.It indicated that the original architectural scheme would probably induce sympathetic vibration of the structure under action of across-wind load.The base moment and the base shear response under action of across-wind load were three times of those under action of leeward-wind load.Through the adjustment of its shape and dynamic characteristic the base moment and the base shear response under action of across-wind load almost eq... |
| Keywords: | elevator-tower high-rise building across-wind load wind-resistant design |
