［摘要］介紹了南京祿口國際機場T2航站樓的結(jié)構(gòu)體系、設(shè)計方法和分析結(jié)果，著重闡述了密切配合建筑造型和空間需求確定鋼屋蓋結(jié)構(gòu)體系的過程。提出了屋蓋相連的分塊混凝土結(jié)構(gòu)整體分析的近似方法和非均布式預(yù)應(yīng)力筋布置方式緩解大尺度混凝土結(jié)構(gòu)溫度應(yīng)力的措施；基于顯式積分方法進行了整體結(jié)構(gòu)動力彈塑性分析，采用瞬態(tài)動力時程分析方法對屋蓋鋼結(jié)構(gòu)進行了結(jié)構(gòu)連續(xù)性倒塌分析，利用荷載位移全過程跟蹤技術(shù)對Y形柱進行了整體穩(wěn)定性分析，最后對幾個關(guān)鍵性節(jié)點的做法進行了介紹。

Abstract: Structural system, design principle, and analysis results of Nanjing Lukou International Airport terminal 2 were introduced. Process of closely incorporating with architectural form and space demand to determine the steel roof system was demonstrated. The approximate global analysis method for segmental concrete structures with continuous roof was proposed. Non-uniform prestress tendon layout to alleviate the impact of temperature stress to large scale concrete structure was studied. The elasto-plastic dynamic analysis to the monolithic structure by using explicit integral method was conducted. Progressive collapse analysis to the steel roof structure by using transient dynamic time history analysis was also conducted. The overall stability to the Y-shaped column by using load-displacement whole process tracking techniques was analyzed and several key joints were-illustrated.

Keywords: airport terminal; structural system selection; large scale concrete structure; large span steel structure; progressive collapse analysis; overall stability
