| Abstract | ||
| Recently, an efficient and practical method has been developed for the generation of univariaternnon-Gaussian wind pressure time histories on low building roofs; this methodology requires intermittentrnexponential random numbers for the simulation. On the other hand, the conventional spectral representationrnscheme with random phase is found suitable for the generation of univariate Gaussian wind pressure timernhistories on low building roofs; this simulation scheme requires uniform random numbers. The dependencyrnof these simulation methodologies on the random number generator is one of the items affecting the accuracyrnof the simultion result; therefore, an attempt has been made to investigate the issue. This note presents thernobserved sensitivity of random number sets in repetitive simulations of Gaussian and non-Gaussian windrnpressures. | ||
