The wind-induced vibrations of super tall buildings become excessive due to strong wind loads

super building height and high flexibility.In real projects

the tuned liquid column damper（TLCD）commonly be used to control the vibration to raise the human comfort.The research on wind-resistant reliability of TLCD was carried out because TLCD may become invalid under the strong wind in cases that dynamic wave height is larger than freeboard or liquid column height.Life cycle cost of super tall building structure-TLCD system was analyzed.Pseudostatic excitation method was employed to calculate stochastic wind-induced vibration response of structureTLCD system under pulsating wind load.Based on first exceedance failure criterion of random vibration

the dynamic reliability of structure-TLCD system under different wind speed loads was researched.Moreover

an innovative life cost model was proposed to evaluate human comfort performance of super tall buildings under wind load.This model evaluated the life cycle cost of the different design schemes

which could help make design choice based on life cost criteria.It is of great significance to the performance-based wind-resistant design.The proposed method was applied to the human comfort design choice of a super tall building with TLCD device to illustrate its effectiveness and applicability.
