A Comparison of Overall Wind Load of Tall Buildings by High Frequency Force Balance and Pressure Integration Method

Abstract

This research is to study the overall wind load acting on tall buildings by the high frequency force balance (HFFB) and high frequency pressure integration (HFPI) . This study present the results of analysis and comparison in terms of non-dimensional aerodynamic coefficients, base overturning moments and Equivalent Static Wind Load (ESWL). The findings from the base moment analysis were compared with the generalized wind force analysis. The results by the base moment analysis demonstrate good agreement between the HFFB and HFPI. The HFFB by the base moment analysis produced lower results than that of the
generalized wind force analysis. On the other hand, the results from the HFPI by the base moment analysis and generalized wind force analysis are identical.
