Abstract EN
In high-frequency force balance (HFFB) wind tunnel tests, the aerodynamic wind loads at the base of the building model are usually amplified by the model-balance system.
This paper proposes a new method for eliminating such an amplification effect.
Firstly, the measured base bending moment signals are decoupled into independent components.
Then, an optimization model is established to represent the problem of identifying the natural frequencies and damping ratios for the different modes of the model-balance system.
Finally, the genetic algorithm (GA) is employed to seek the solution to the optimization problem, and the base bending moment is corrected through the identified dynamic parameters of the model-balance system.
Compared to the conventionally used knocking method, the proposed method requires no extra knocking tests and can take the aerodynamic damping of the model-balance system into account.
An engineering case, the Guangzhou East Tower (GZET), is taken as an example to show the effectiveness of the method.
