Abstract
<p>Dry cable galloping is one of hazardous phenomena that could be observed in long circular cylindrical members such as stay cables. The authors previously conducted a series of wind tunnel tests where an inclined circular cylinder model was supported as a pendulum and windinduced response at high wind speed range was observed. In this study, in order to clarify the mechanism of the vibration, the fluctuating wind pressure was measured using MEMS sensors installed in the model. Because the sensors were controlled by wireless LAN, the model response was basically the same as the previous test. From the obtained phase averaged wind pressure distribution, the aerodynamic force acting on the model was found to have some phase lag from quasi-steady theory when the model was at its maximum and minimum amplitude. In order to have clear understanding, details have to be studied further.</p>
