ABSTRACT

This paper tries to find the efficient way of measuring the wind speeds of bridge members with a prototype wind pressure sensor. We installed six wind pressure sensors at the tower and the girder of a bridge and calculated the average wind speeds per 10 minute of the northeast and the southeast winds. We used the equation for converting wind pressure to wind speeds and the Korean high way design code for revising the altitude of the tower and the girder. For the sensitive analysis of our measurement, we conducted the same test by installing the sensor on a car. From the test, we find that the winds are more likely to come from the northeast and the speeds converted from wind pressure are greater than one measured by wind speed sensors. However, there is no significant difference of wind speeds between two methods at CH3. Therefore, we argue that the method of measuring wind speeds covered from wind pressure is effective in evaluating the wind speeds of a bridge member.
