[摘要] 锦城艺术宫改扩建工程写字楼由于功能需要在局部楼层形成无柱大空间，使结构面临二次高位转换的难题。对应不同建筑方案分别提出了钢结构巨型框架体系和钢结构框架-支撑体系结合转换桁架两种结构方案，并通过初步计算对两种方案的可行性进行了研究。

Abstract: Because of function necessary to form large column-free space at the local floor, The project of reconstruction and extension of Jincheng Arts Palace face to the second-high-conversion problem. Mega-frame steel structure and steel braced-frame structure combined with transfer truss are mentioned separately according to different building programs, and through a preliminary calculation, the feasibility of the two types of programs are researched.
Keywords: mega-frame; braced-frame structure; large space; second-lugh-conversion; transfer-truss; feasibility
