摘　　要：300 m以上超高层建筑为加强本身对大地震的抗震性能,均设置一道或一道以上的桁架层;桁架层构件多,体量大,连接多,节点复杂,桁架层外框劲性混凝土大巨柱是桁架层结构的重中之重,施工难度大,质量要求高。结合长沙国金中心项目工程实例,就如何保证超高层建筑桁架层劲性混凝土大巨柱施工的质量、成本和工期进行详细的介绍。The super high-rise buildings with a height of 300m or more are provided with one or more truss layers for strengthening the seismic performance of large earthquakes; there are many truss layers, large volumes, many connections, and complex nodes, and the concrete columns of the truss floor are stiff. The truss layer structure is of the highest priority, and the construction is difficult and the quality requirements are high. In this paper, combined with the project of the Changsha International Finance Center project, a detailed introduction is provided on how to ensure the quality, cost, and duration of the construction of a super high-rise building truss-story concrete column.
