In recent years, numerous super-tal

In recent years, numerous super-tall buildings have been or arebeing built throughout the world. As modern high-rise buildingsbecome higher and more flexible than those in the past, evaluationof wind loads is the key factor in their structural design. At present,wind tunnel testing is a relatively mature technique for estimatingwind effects on buildings and structures. However, it is difficult toreproduce the exact field conditions such as incident turbulenceand terrain characteristics as well as Reynolds number in windtunnel tests. Field measurement is regarded as the most reliableway for evaluating the wind effects on prototype buildings andstructures. Nevertheless, it is infeasible to directly measure thewind loads on a tall building by field measurements due to thefacts such as high cost of force transducers or/required transducersmight not even exist. Consequently, it would be beneficial if thewind forces could be determined indirectly using measuredwind-induced responses of high-rise structures.
