[摘要] 奈伦国贸是一栋双塔连体超高层建筑。由于建筑功能、楼层净高和建筑立面的限制，建筑外框由密柱转换稀柱采取了三种转换形式：钢管混凝土桁架式转换、双层梁式转换和越层梁式转换。本文介绍了针对这三种转换形式的分析和处理方法，并提出了转换部位的构造设计和施工质量控制要求。

Abstract: Nailun Intemational Trade Center is a super tall building consists of two towers. In order to satisfy the architecture functions and exhibitions, three kinds of transfer members are adapted in this engineering. They are transfer truss with concrete-filled steel tubular members, double-story transfer beams, and transfer beam with height beyond the story. In this article, analysis methods areintroduced, and the construction details and construction quality demands are present.
Keywords: super tall building, transfer truss, concrete-filled tubular, double-story transfer beams
