| Popis: | 103 Buildings under wind loads result in along-wind, across-wind and torsional wind load effects; vectorial wind load effects are their nonlinear combinations. This study concerns the building top floor corner maximum acceleration and derives new formula considering the correlation between the wind load effects. First, wind load spectra are obtained by numerical simulations, and the results are compared with those from wind tunnel tests. The correlation coefficients between accelerations depend on the normalized wind load spectra, the fundamental natural frequencies and damping ratios. In this study, two formula have been derived; the difference is that formula 1 adopts an octagonal approximation while formula 2 adopts a CQC rule. Finally, the results of the above two formula are compared with those from design code. It is found that formula 2 provides the most accurate results; the results based on design code are slightly conservative; formula 1 generally yields the most conservative results. |
