Estimation of Wind Load on Stepped Tall Building Using CFD Simulation

Abstract

The behavior of wind around stepped tall building is quite different comparing with the symmetric plan shape tall building. Setback roof of stepped buildings is widely responsible for the turbulence around the building. The purpose of this work is to understand the behavior of wind load on stepped tall building model. Four different models having the same dimensions and same aspect ratios but different setback distances, namely Models A, B, C and D, are considered. The setback distances are 0.2L, 0.3L, 0.4L and 0.5L (L = length) and are located at H/2 level (H = height) from the base of domain. Computational fluid dynamics simulations are taken out of terrain category 2 with the model scale 1:300. The foreground of this study is the external pressure and force variation around the building face and roof at 0° and 90° wind incidence angles. Maximum positive pressure coefficient develops at 90% of building height from the base of all models and for setback case it goes to 80%. Negative pressure develops at the building roof top, whereas positive pressure develops in the setback roof for the same model and wind angle. This type of pressure variable will be considered in roof design of stepped building.
