摘　　要：A380机库大厅跨度352.6m,其东侧仅在跨中设有一个支撑柱,柱顶采用大吨位铸钢节点及抗震支座支撑。该铸钢节点及抗震支座受力大,结构复杂。施工中采用先焊接铸钢节点和抗震支座,然后进行桁架梁合龙,再进行抗震支座和柱顶埋件焊接,施工进度和施工质量都得到了保证。Lobby span of A380 Aircraft Hangar is 352.6m. At east part of the lobby, only one supporting column is set at mid-span, and column top is supported by large-tonnage cast steel node and quake-proof bearing, which bear big force and have complicated structures. Cast steel node and quake-proof bearing are welded first, then girder truss is connected, and finally quake-proof bearing and embedded members on column top are welded together. In this way, ideal construction schedule and quality are achieved.
