摘要: 陆侧交通中心是联系杭州萧山国际机场 T1 ~ T4 各航站楼的中转站,是杭州萧山国际机场三期工程的核心部分。 对陆侧交通中心及上盖结构体系进行了介绍,根据项目特点及规范合理选取了设计参数及抗震性能目标。采用对比分析方法确定地下室顶板作为嵌固端,使结构传力体系简单明了,并采用 YJK 软件分析了结构动力特性。采用实体有限元方法对菱形网格网壳钢屋盖及采光顶受力特性进行了研究,同时对上部多塔超长结构进行了温度作用分析,分析结果表明结构布置、构件设计参数及性能目标经济合理。 另外,弹塑性时程分析结果表明在罕遇地震作用下结构抗震性能良好。

Abstract:Landside traffic center is a transfer station connecting T1 ~ T4 terminals of Hangzhou Xiaoshan InternationalAirport and the core part of phase Ⅲ project of Hangzhou Xiaoshan International Airport. The landside traffic center andthe upper cover structure system were introduced, and the design parameters and seismic performance targets according tothe project characteristics and specifications were reasonably selected. The basement roof was determined as the embeddedend by the comparative analysis method, which makes the structure force transfer system simple and clear. The dynamiccharacteristics of the structure were analyzed by YJK software. The stress characteristics of diamond grid shell steel roof anddaylighting roof were studied by using the solid finite element method, and the temperature effect of the upper multi towersuper-long structure was analyzed. The analysis results show that the structural layout, member design parameters andperformance targets are economical and reasonable. In addition, the elastoplastic time history analysis results show that theseismic performance of the structure is good under the rare earthquake.
