Journal ArticleDOI
Characteristics of wind forces acting on tall buildings
TL;DR: In this article, the effects of three parameters, elevation, aspect ratio, and side ratio, on bluff-body flow and thereby on the local wind forces are discussed, and the overall loads and base moments are obtained by integration of local wind force coefficients.
Journal ArticleDOI
Pressure distributions on a cube in a simulated thunderstorm downburst—Part A: stationary downburst observations
M.T Chay,Chris Letchford +1 more
TL;DR: In this article, a study aimed at simulating the flow structure in a downburst and obtaining the pressure field on a cube immersed in such a flow is presented, where the data obtained from a stationary wall jet simulation of a thunderstorm downburst is compared with data from uniform and boundary layer flows.
Journal ArticleDOI
A deterministic¿stochastic hybrid model of downbursts and its impact on a cantilevered structure
Lizhong Chen,Chris Letchford +1 more
TL;DR: In this article, a deterministic-stochastic hybrid model of downbursts is presented, where the downburst winds are the summation of deterministic mean and a stochastic fluctuation.
Journal ArticleDOI
A forensic study of the Lubbock-Reese downdraft of 2002
TL;DR: In this article, the authors discussed engineering aspects of the rear-flank downdraft that was recorded near Lubbock, Texas on 4 June 2002, and produced a gust wind speed nearly equal to the design value (50-year return period) for the region.
Journal ArticleDOI
Thunderstorms—their importance in wind engineering (a case for the next generation wind tunnel)
TL;DR: A state-of-the-art summary of research into thunderstorm wind fields from an engineering perspective can be found in this paper, where the characteristics of thunderstorms and the two extreme wind events-tornadoes and downbursts-spawned by thunderstorms are described.
