摘要: 拉薩貢嘎機場 T3 航站樓功能上主要包括中心區(qū)值機大廳和兩側(cè)的候機指廊區(qū)兩部分,其主體結(jié)構(gòu)由下部的混凝土框架結(jié)構(gòu)和上部的鋼結(jié)構(gòu)屋面組成。 中心區(qū)值機大廳屋面幾何形態(tài)似四片蓮花花瓣,采用 12 根樹形柱支撐,每根樹形柱上部又由 4 根分叉柱組成,分叉柱兩端采用向心關(guān)節(jié)軸承節(jié)點;屋面采用雙向鋼桁架結(jié)構(gòu)體系,并利用拓撲優(yōu)化技術(shù)分析了屋面的最佳傳力路徑。 候機指廊區(qū)屋面采用實腹式鋼梁結(jié)構(gòu)體系,降低了結(jié)構(gòu)高度,有利于解決凈空問題。 設計團隊利用 BIM 三維建模方式,實現(xiàn)了結(jié)構(gòu)-機電專業(yè)的一體化協(xié)同設計。

Abstract: Lhasa Gonggar Airport Terminal 3 mainly includes a check ̄in hall in the central area and the waiting corridor onboth sides. Its main structure is composed of a lower concrete frame structure and an upper steel structure roof. Thegeometric shape of the roof of the check ̄in hall in the central area resembles four lotus petals, supported by 12 tree ̄shapedcolumns, and the upper part of each tree ̄shaped column is composed of 4 bifurcated columns, both ends of the bifurcatedcolumns adopt centripetal joint bearing nodes. The roof adopts a two ̄way steel truss structure system, and the besttransmission path of the roof was analyzed using topology optimization technology. The roof of the waiting corridor areaadopts a solid ̄web steel beam structure system, which reduces the structural height and is conducive to solving theclearance problem. The design team used BIM three ̄dimensional modeling to realize the integrated collaborative design ofstructure ̄mechanical and electrical engineering.
Keywords: Lhasa Gonggar Airport; topology optimization; tree ̄shaped column; centripetal joint bearing nodes; BIM three ̄dimensional modeling; collaborative design
