Abstract

With advances in wind tunnel methodologies in recent years, the measurement of wind loads on wind tunnel models of buildings and structures can be carried out with a high degree of accuracy. These results lead to more economical and risk-consistent structural designs than do code calculation methods. Five topics related to the prediction of cladding design wind pressures are examined in this paper: (1) wind tunnel testing and analysis methods, (2) integration of wind tunnel data with the full-scale wind climate, (3) evaluation of internal pressures, (4) duration of constant wind pressure for determining the load resistance of glass, and (5) computational fluid dynamics (CFD).

Keywords:
cladding design, wind tunnels, wind climate, internal pressures, load duration, CFD
