To solve this problem, this paper proposed a design method of giant composite component based on life cycle economic cost. The life-cycle cost of giant composite component mainly contains initial cost, maintenance cost, failure cost caused by hazard and demolition cost. The proposed method firstly calculates all life-cycle costs of giant composite component and then selects the optimal design scheme by data’s collection and comparison. The overall schemes’ analysis and selection will be done at the initial phase of the structural project if this method can be employed. The proposed method is applied to a super tall building to illustrate its effectiveness and applicability.Keywords: super-tall structure, the giant composite structural component, life cycle, economic cost*上海市科技攻關(guān)計劃資助（編號：09dz1207704）；上海市青年科技啟明星計劃（跟蹤）資助（編號：11QH1402700）。通訊作者：姜世鑫，Email: jiang15210@163.com。
