Abstract
This study examines deviations in peak pressures among different facets of a ‘Z’ shaped building model tested using numerical simulation technique. Peak suction and pressure for each face and the variation of gust factor (GF) along the vertical centerline of different walls of the parametric model corresponding to 0° and 90° wind angle are presented. For this purpose, the unsteady Reynolds Averaged Navier–Stokes (URANS) Computational Fluid Dynamics (CFD) simulation tool with the k-ε turbulence model is adopted. The geometric scale is taken as 1:300 and the velocity scale is 1:5. Contour plots showing changes of peak pressure at different locations of each face are also presented in the study. The dynamic effects of wind on tall structures are evaluated by gust factor in most of the available wind standards globally. The gust factor thus obtained in this particular study may be used to derive an equivalent static load for design purposes of ‘Z’ shaped in plan tall buildings to assess the wind force with sufficient precision. Finally, the characteristics of the wind power spectra are presented at the building’s top on different facets under orthogonal wind directions.
