Effect of Measurement Points Number on The Layered Wind Force Using Multi-channel Pressure Measured Simultaneously

Abstract

When performing layered wind power evaluation by simultaneous wind pressure measurement at multiple points, the measurement points are arranged discretely. Therefore, a discretization error occurs. Discretization error is evaluated by comparing it with an experiment using a device called a "balance". However, before making a wind pressure model, we need to know how many wind pressure measurement points should be installed for the complex shape of a real building.

In this report, we will introduce a study using a wind pressure model in which measurement points are densely arranged. We focused on the top of the model and the two layers near the stagnation point. The effect of measurement point density on layer wind power and layer torsional moment was investigated. The target building has a flat shape. In order to obtain measurement accuracy in this building, it is necessary to arrange eight or more wind pressure measurement points on the long side.
