Fluctuating wind loads on roof components
Abstract
Analysis of pressures measured on the roof of the full-scale Texas Tech building and a 1/50 scale model of a typical house showed that the pressure fluctuations on cladding fastener and cladding-truss connection tributary areas have similar characteristics. The probability density functions of pressure fluctuations on these areas are negatively skewed from Gaussian, with pressure peak factors less than -5.5. The fluctuating pressure energy is mostly contained at full-scale frequencies of up to ~ 0.6 Hz. AS 1170.2 prescribes generally satisfactory Cp and Kl values, albeit unconservative for small areas near the edges.
