Accumulation Coefficients

Snowdrift patterns exhibit various forms according to the architectural shapes and models. As snowdrift patterns largely influence the snow loads that buildings have to withstand, a number of studies have been conducted. This study examines snowdrift patterns and how the amount of snow comes to rest depends on the shape of a roof (for flat and gable roofs) using a wind tunnel test. An analysis of snowdrift patterns and accumulation coefficients, which are representative of the depth of snow cover, for flat and gable roofs showed that accumulation coefficient decreases in accordance with increases in wind speed. The gable roof exhibited a slightly higher accumulation coefficient than the flat roof.

Processing Requirement

Data post-processing plays important roles in a wind tunnel test, especially in supporting the validation of the test results and further data analysis related to the design activities of the test objects. One effective solution to carry out the data post-processing in an automated productive manner, and thus eliminate the cumbersome conventional manual way, is building a software which is able to execute calculations and have abilities in presenting and analyzing the data in accordance with the post-processing requirement. Through several prototype development cycles, this work attempts to engineer and realize such software to enhance the overall wind tunnel test activities.

High Rise Building

Experimental wind tunnel test results are affected by acquisition times because extreme pressure peak statistics depend on the length of acquisition records. This is also true for dynamic tests on aeroelastic models where the structural response of the scale model is affected by aerodynamic damping and by random vortex shedding. This paper investigates the acquisition time dependence of linear transformation through singular value decomposition (SVD) and its correlation with floor accelerometric signals acquired during wind tunnel aeroelastic testing of a scale model high-rise building. Particular attention was given to the variability of eigenvectors, singular values and the correlation coefficient for two wind angles and thirteen different wind velocities. The cumulative distribution function of empirical magnitudes was fitted with numerical cumulative density function (CDF). Kolmogorov–Smirnov test results are also discussed.
