Abstract

In this paper, experiments and finite-element analyses are used to investigate the wind-induced vibration in high-tech factories. The experimental results during the Megi typhoon on September 27, 2016, indicated that wind-induced vibration cannot be ignored in high-tech factories, while horizontal vibration is much larger than the vertical one, and the vibration at the first natural frequency of the building is obviously dominant for the wind-induced vibration. Moreover, a reinforced concrete level can meet the vibration criteria at more severe wind conditions than a steel level is able to. In the finite-element analysis, the TurbSim version 1.06.00 software package is used to generate the time-dependent turbulence wind speed field, and the finite-element results are calibrated with the experimental measurements. The finite-element parametric study then indicates that a reduction in the floor vibration of a high-tech factory is feasible due to the shade of adjacent buildings. However, this reduction is negligible when the height of the shading building is not more than 60% of the factory height. For high-tech factories with long span trusses, increasing the member sizes to reduce wind-induced vibration, including the bracing, wall, and column members, may not be efficient and should be considered conservatively.
