| Abstract | This paper presents the analysis of the modal correlation coefficient and the weighting factor for predicting wind load combination in tall buildings under wind loads by high-frequency force balance (HFFB) and high-frequency pressure integration (HFPI) in a wind tunnel. The results of the analysis and comparisons in terms of non-dimensional aerodynamic coefficients and base moments will be presented in this study, to determine whether the pressure tap on the model surface for the HFPI test is sufficiently dense. Results show good agreement between HFFB and HFPI for overall wind loads, modal correlation coefficients and weighting factors. Wind load combinations are revisited in the framework of modeling the resultant base moments in each direction. According to the findings, the across-wind load combination by weighting factor is higher than the across-wind load combination by AIJ 2004 standard for the along-wind maximum case for buildings with an aspect ratio of 1.0. In other cases, the combination of wind loads as determined by AIJ 2004 is greater than the combination of wind loads determined by the weighting factor. |
