Abstract: To accurately identify the nonlinear damping ratio of tall buildings, the authors propose an envelope random decrement technique (RDT). To verify the accuracy of the envelope RDT for the evaluation of amplitude-dependent ...

Abstract: This paper aims to accurately calculate the time-varying standard deviation of nonstationary wind speed by modeling wind speed as a time-varying mean wind speed plus a uniformly modulated nonstationary process and applying ...

Abstract: The loads on buildings and structures caused by the buffeting action of wind have traditionally been analyzed using the gust loading factor (GLF) approach in most codes and standards. In this approach, the equivalent static ...

Abstract: Traditionally, wind analysis procedures based on the “gust loading factor” approach and experimental techniques involving the high frequency base balance and the “stick-type” aeroelastic model test have assumed ideal ...

Abstract: The sinusoidal reference strategy (SRS) is a new strategy developed by the present authors for adaptive feedforward vibration control. The recursive-least-squares algorithm is used and a higher frequency sinusoidal signal ...

Abstract: Stochastic wind velocity fields are usually simulated as
