“…Initial wind tunnel data including mean loads on PTSCs were reported in Peterka et al (1980) and Randall et al (1980Randall et al ( , 1982 under contract from Sandia National Laboratories. In order to account for the dynamic behaviour of wind loads, peak load coefficients are estimated from mean load coefficients using a gust factor approach (see, e.g., Liu, 1990).…”
