| Abstract |
Across-wind fluctuating pressures on a square tall building is high local suctions that tend to dislodge the cladding. This causes the failure of cladding as well as fastener. Across-wind fluctuating pressures has non-Gaussian distribution, which is found to induce increased fatigue damage compared to Gaussian distribution. Simulation method is useful when a number of fluctuating pressure time histories are required to carry out extreme value analysis and fatigue design. The spectral correction method makes use of the backward and forward hermite transformation and is capable of matching a target power spectrum and four target moments. In this paper, the application of non-Gaussian simulation method using spectral correction method to the across-wind fluctuating pressures on a square tall building is assessed by comparing measured pressures in boundary-layer wind tunnel tests on scale models with simulated pressures. |
