Study on Development of Tornado-induced Wind Load Model

Part 2: Simulation of Internal Pressures Considering Translation Effect of Tornado-like Wind

Abstract

In this study, numerical simulation of internal pressure is carried out by applying external wind pressure data obtained from wind pressure experiments to the past proposed model. The purpose of this simulation is to understand mechanism of the internal pressure generation under the translation effect of tornado-like wind. The numerical result shows that the past model can properly simulate internal pressure characteristics obtained from the experiments. Next, the way to estimate internal pressure characteristics under the translation effect is studied by associating translation speed with additional coefficient composing of the past model.
