摘要: 陸側(cè)交通中心是聯(lián)系杭州蕭山國際機(jī)場 T1 ~ T4 各航站樓的中轉(zhuǎn)站,是杭州蕭山國際機(jī)場三期工程的核心部分。 對陸側(cè)交通中心及上蓋結(jié)構(gòu)體系進(jìn)行了介紹,根據(jù)項目特點及規(guī)范合理選取了設(shè)計參數(shù)及抗震性能目標(biāo)。采用對比分析方法確定地下室頂板作為嵌固端,使結(jié)構(gòu)傳力體系簡單明了,并采用 YJK 軟件分析了結(jié)構(gòu)動力特性。采用實體有限元方法對菱形網(wǎng)格網(wǎng)殼鋼屋蓋及采光頂受力特性進(jìn)行了研究,同時對上部多塔超長結(jié)構(gòu)進(jìn)行了溫度作用分析,分析結(jié)果表明結(jié)構(gòu)布置、構(gòu)件設(shè)計參數(shù)及性能目標(biāo)經(jīng)濟(jì)合理。 另外,彈塑性時程分析結(jié)果表明在罕遇地震作用下結(jié)構(gòu)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.
Keywords:Hangzhou Xiaoshan International Airport; multi tower super-long structure; embedded end; temperature stress;eastoplastic time history analysis; diamond grid
