Abstract
When the pressures on both sides of walls or roofs are measured simultaneously, or when the local pressures at a pointed or complicated shaped portion is measured, pipes or tubes connecting the pressure tap and the pressure transducer must be bent at rather acute angles. This paper discusses the applicability of bent pipes based on experimental results on its effects on fluctuating wind pressure signals. The experimental results have clarified that both the position of bend and the number of bend points can nearly be ignored, and that the effects of the sectional area of the bend point can be ignored when a brass bar with the same diameter as the inside diameter of the pipe is inserted into the pipes before they are bent.
