Analysis of wind pressure coefficients on CTBUH standard high-rise buildings in CFD simulations

Abstract

At present with the fast growth rate of population constructing high-rise buildings has been a common trend for many urban communities, so it is important to analyze wind pressure around and over these high-rise structures. CFD analysis is an effective way to understand this, in which CTBUH (Council on Tall Buildings and Urban Habitat) standard high-rise building has been a recognized model to validate and calibrate high-rise building models. As it may, less work has been directed to study of airflow around CTBUH standard high-rise building to geometric and computational parameters in CFD analysis. In this investigation is therefore intended to fill this gap by analyzing effects of various parameters like turbulence model, approaching-flow speed and grid type on wind pressure coefficients over CTBUH structures. Wind pressure coefficients around CTBUH models subjected to three wind directions were numerically analyzed for validating the correctness and effectiveness of numerical model. In conclusion acquired results can help structural engineers to choose empirical geometric and computational parameters in anticipating wind pressure distribution against high-rise buildings.At present with the fast growth rate of population constructing high-rise buildings has been a common trend for many urban communities, so it is important to analyze wind pressure around and over these high-rise structures.
