| 摘 要： | 凯晨广场为三塔连体结构,设计中从概念入手,对一般三塔连体结构的振型参与系数进行理论分析,了解连体部位在地震作用下的反应规律,合理选择连体与主体部分的连接方式。通过提高连体与主体连接部位抗震等级,采取特殊构造措施等方法,加强连体部位与主体结构的连接。最后通过静力弹塑性分析,研究了结构在罕遇地震下结构的性能。结果表明,通过采用适度的加强措施,在其他构件均已出现塑性铰的情况下,连接部位依然可以保持弹性。

| Abstract: | Chemsunny Plaza is a structure with three-connected-tower.Typical connected structure's modal participation factor was analyzed theoretically for concept design,through which reasonable structure system and connection were constructed.The connection of bridge and main structure was enhanced by improving the level of earthquake resistance and special construction measures.Static nonlinear analysis result shows that connection remains elastic at infrequency earthquake while other members have turned into inelastic. |
