摘　　要：西安某小学地上5层,房屋高度20.5m。出入口位置因消防通道原因,存在两层架空,角部位置因建筑造型原因存在大悬挑,采用型钢构件组成的桁架结构进行架空转换和出挑。本文主要介绍该建筑的大跨度架空转换层和大跨度悬挑的结构设计过程,从结构规则性、架空转换层、悬挑桁架三个方面进行阐述与分析。结果表明,该结构安全合理,抗震性能良好。A primary school in Xi'an has 5 floors above ground and a house height of 20.5m.Due to the fire passage,there are two floors of overhead structures at the entrance and exit,and there is a large overhang at the corner due to the architectural design.A truss structure composed of shaped steel components is used for overhead conversion and overhanging,This article mainly introduces the structural design process analysis of the large-span overhead transfer layer and large-span cantilever of the building.Elaborate and analyze the design from three aspects:structural regularity,overhead transfer layer,and cantilever truss.The results indicate that the structure is safe and reasonable,with good seismic performance.

关 键 词：结构规则性 架空转换层 悬挑桁架
