摘　　要：拉萨贡嘎机场T3航站楼功能上主要包括中心区值机大厅和两侧的候机指廊区两部分,其主体结构由下部的混凝土框架结构和上部的钢结构屋面组成。中心区值机大厅屋面几何形态似四片莲花花瓣,采用12根树形柱支撑,每根树形柱上部又由4根分叉柱组成,分叉柱两端采用向心关节轴承节点;屋面采用双向钢桁架结构体系,并利用拓扑优化技术分析了屋面的最佳传力路径。候机指廊区屋面采用实腹式钢梁结构体系,降低了结构高度,有利于解决净空问题。设计团队利用BIM三维建模方式,实现了结构-机电专业的一体化协同设计。Lhasa Gonggar Airport Terminal 3 mainly includes a check-in hall in the central area and the waiting corridor on both sides. Its main structure is composed of a lower concrete frame structure and an upper steel structure roof. The geometric shape of the roof of the check-in hall in the central area resembles four lotus petals, supported by 12 tree-shaped columns, and the upper part of each tree-shaped column is composed of 4 bifurcated columns, both ends of the bifurcated columns adopt centripetal joint bearing nodes. The roof adopts a two-way steel truss structure system, and the best transmission path of the roof was analyzed using topology optimization technology. The roof of the waiting corridor area adopts a solid-web steel beam structure system, which reduces the structural height and is conducive to solving the clearance problem. The design team used BIM three-dimensional modeling to realize the integrated collaborative design of structure-mechanical and electrical engineering.
