［摘要］鄭州興港大廈為鄭州航空港經(jīng)濟綜合實驗區(qū)新建辦公、酒店、商業(yè)綜合體項目，由兩棟塔樓以及采用高位弱連接形式的連接體組成。在初步設(shè)計階段，針對連體結(jié)構(gòu)的特點，對幾個結(jié)構(gòu)關(guān)鍵問題進行了分析、設(shè)計與研究。對本工程連體結(jié)構(gòu)采用弱連接連體結(jié)構(gòu)體系的原因進行了說明。通過連體結(jié)構(gòu)與單體結(jié)構(gòu)的小震彈性時程對比分析得出，本工程連接體對兩端主體結(jié)構(gòu)的影響不大。對連體結(jié)構(gòu)進行了罕遇地震作用下的邊界非線性分析，為連體結(jié)構(gòu)防震縫寬度的確定以及鉛芯橡膠隔震支座的選擇提供了依據(jù)。對大跨度連接體進行了人行荷載激勵下的數(shù)值模擬，驗算了連接體的豎向振動舒適度。

Abstract: Zhengzhou Xinggang mansion is a new office, hotel and commercial complex project of Zhengzhou airport economic general experimentation area. The single body is composed of two towers and the connection body which adopts the high level and weak connection form. In the preliminary design stage, several key problems of the structure were analyzed, designed and studied according to the characteristics of the connected structure. The reasons for adopting the weak connection form in this project were introduced. Through the comparison of the elastic time history analysis of the single structure and the connected structure, it is indicated that the conector has little effect on the main structure of the two ends. The boundary nonlinear analysis of the connected structures under sevre earthquake is carried out, which provides a basis for determining the width of the joints and the selection of the lead rubber bearings. The numerical simulation of the large span connector was carried out under the walking load excitation, and the vertical vibration comfort of the connector was checked.
Keywords: connected structure; isolation bearing; vibration serviceability; nonlinear analysis
