Higher Mode Effects on Wind Loads and Responses of Tall Buildings

This paper presents wind-induced response of tall buildings based on High Frequency Pressure Integration (HFPI) tests. The Generalized Wind Force Analysis are used to analyze the data obtained from the HFPI test to determine the contributions of higher modes to building responses (top displacement, top acceleration, base moments in along-wind, across-wind and torsional directions). The results show that the fundamental mode is adequate for the top displacement and base overturning moment of square tall buildings but neglecting the contribution of higher modes may result in an underestimate of the top acceleration response in wind direction.
